Albert Einstein was a German-born theoretical physicist known for his groundbreaking contributions to the field of physics. He developed the theory of relativity and made important contributions to quantum mechanics, reshaping our understanding of nature in the early 20th century. His equation E = mc2, which arises from relativity theory, is famous worldwide. In 1921, he received the Nobel Prize in Physics for his discovery of the law of the photoelectric effect. Einstein's work has had a significant influence on the philosophy of science and he is widely regarded as one of the greatest physicists of all time.

Throughout his career, Einstein made remarkable achievements. In 1905, often called his annus mirabilis (miracle year), he published four groundbreaking papers that explained the photoelectric effect, Brownian motion, and introduced his special theory of relativity. He also demonstrated the equivalence between mass and energy. In 1915, he proposed a general theory of relativity that incorporated gravitation into his system of mechanics. His cosmological paper in 1916 explored how general relativity could explain the structure and evolution of the universe. Additionally, Einstein contributed to statistical mechanics and quantum theory during this phase.

Despite these successes, Einstein faced difficulties later in his academic life. He opposed randomness in quantum theory while attempting to develop a unified field theory that combined gravity and electromagnetism but failed ultimately. Consequently, he became isolated from modern physics' mainstream during this time.

Born in Germany, Einstein moved to Switzerland in 1895 and acquired Swiss citizenship. He studied at Zurich's Federal polytechnic school before joining the Swiss Patent Office in Bern where he secured a permanent position. Einstein obtained his PhD from the University of Zurich in 1905. Later, he moved to Berlin and became director of the Kaiser Wilhelm Institute for Physics. When Adolf Hitler rose to power in Germany in 1933, Einstein decided to remain in the US, where he was granted American citizenship in 1940. He endorsed a letter to President Franklin D. Roosevelt urging research into nuclear weapons but viewed the idea with dismay.

“I never think of the future. It comes soon enough.”

Attributed in The Encarta Book of Quotations http://books.google.com/books?id=Af84fBmzmVYC&pg=PA305&dq=Belgenland to an interview on the Belgenland (December 1930), which was the ship on which he arrived in New York that month. According to The Ultimate Quotable Einstein by Alice Calaprice (2010), p. 18 http://books.google.com/books?id=G_iziBAPXtEC&lpg=PP1&pg=PA18#v=onepage&q&f=false, the quote also appears as "Aphorism, 1945-1946" in the Einstein Archives 36-570. Calaprice speculates that "perhaps it was recalled later and inserted into the archives under the later date." According to a snippet on Google Books, the phrase '"I never think of the future," he said. "It comes soon enough."' appears in The Literary Digest: Volume 107 on p. 29, in an article titled "We May Not 'Get' Relativity, But We Like Einstein" from 27 December 1930 http://books.google.com/books?id=T0A_AAAAMAAJ&q=%22we+like+einstein%22#search_anchor. The snippet http://books.google.com/books?id=T0A_AAAAMAAJ&q=belgenland+%22I+never+think+of+the+future%22+%22it+comes+soon+enough%22#search_anchor also discusses the "welcome to Professor Einstein on the Belgenland" in New York

“I live in that solitude which is painful in youth, but delicious in the years of maturity.”

"Self-Portrait" (1936), p. 5 http://books.google.com/books?id=Q1UxYzuI2oQC&lpg=PP1&pg=PA5#v=onepage&q&f=false
1950s, Out of My Later Years (1950)
Variant: I live in that solitude which is painful in youth, but delicious in the years of maturity.

“What a sad era when it is easier to smash an atom than a prejudice.”

Variant: What a sad era when it is easier to smash an atom than a prejudice.

“Weakness of attitude becomes weakness of character”

Speech made in honor of Thomas Mann in January 1939, when Mann was given the Einstein Prize given by the Jewish Forum. Quoted in Einstein Lived Here by Abraham Pais (1994), p. 214 http://books.google.com/books?id=u_9QAAAAMAAJ&q=%22becomes+lack+of+power%22#search_anchor
1930s
Context: The standard bearers have grown weak in the defense of their priceless heritage, and the powers of darkness have been strengthened thereby. Weakness of attitude becomes weakness of character; it becomes lack of power to act with courage proportionate to danger. All this must lead to the destruction of our intellectual life unless the danger summons up strong personalities able to fill the lukewarm and discouraged with new strength and resolution.

“Much reading after a certain age diverts the mind from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking,”

1930s, Wisehart interview (1930)
Context: Much reading after a certain age diverts the mind from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theaters is apt to be content with living vicariously instead of living his own life.

“I love Humanity but I hate humans”

A comment of Einstein's recalled by John Wheeler in Albert Einstein: His influence on physics, philosophy and politics edited by Peter C. Aichelburg, Roman Ulrich Sexl, and Peter Gabriel Bergmann (1979), p. 202
Attributed in posthumous publications
Variant: I love to travel, but I hate to arrive.

“Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.”

“I believe in intuition and inspiration.”

Cosmic Religion : With Other Opinions and Aphorisms (1931) by Albert Einstein, p. 97; also in Transformation : Arts, Communication, Environment (1950) by Harry Holtzman, p. 138. This may be an edited version of some nearly identical quotes from the 1929 Viereck interview below.
1930s
Context: I believe in intuition and inspiration. … At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

“My religion consists of an humble admiration for the vast power which manifests itself in that small part of the universe which our poor, weak minds can grasp!”

1930s, Wisehart interview (1930)
Context: I do not believe in a God who maliciously or arbitrarily interferes in the personal affairs of mankind. My religion consists of an humble admiration for the vast power which manifests itself in that small part of the universe which our poor, weak minds can grasp!

“Without "ethical culture," there is no salvation for humanity.”

"The Need for Ethical Culture" celebrating the seventy-fifth anniversary of the Ethical Culture Society, founded by Felix Adler (5 January 1951) (the full remarks can be found in Ideas and Opinions by Albert Einstein and Carl Seelig http://books.google.com/books?id=UppFAAAAYAAJ)
1950s
Context: I believe, indeed, that overemphasis on the purely intellectual attitude, often directed solely to the practical and factual, in our education, has led directly to the impairment of ethical values. I am not thinking so much of the dangers with which technical progress has directly confronted mankind, as of the stifling of mutual human considerations by a "matter-of-fact" habit of thought which has come to lie like a killing frost upon human relations. … The frightful dilemma of the political world situation has much to do with this sin of omission on the part of our civilization. Without "ethical culture," there is no salvation for humanity.

“I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem—the most important of all human problems.”

Attributed in posthumous publications, Einstein and Religion (1999)
Context: It seems to me that the idea of a personal God is an anthropomorphic concept which I cannot take seriously. I feel also not able to imagine some will or goal outside the human sphere. My views are near to those of Spinoza: admiration for the beauty of and belief in the logical simplicity of the order and harmony which we can grasp humbly and only imperfectly. I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem—the most important of all human problems.

From a letter to Murray W. Gross (26 April 1947), p. 138

“There are pessimists who hold that such a state of affairs is necessarily inherent in human nature; it is those who propound such views that are the enemies of true religion, for they imply thereby that religious teachings are Utopian ideals and unsuited to afford guidance in human affairs.”

1940s, Religion and Science: Irreconcilable? (1948)
Context: While religion prescribes brotherly love in the relations among the individuals and groups, the actual spectacle more resembles a battlefield than an orchestra. Everywhere, in economic as well as in political life, the guiding principle is one of ruthless striving for success at the expense of one's fellow men. This competitive spirit prevails even in school and, destroying all feelings of human fraternity and cooperation, conceives of achievement not as derived from the love for productive and thoughtful work, but as springing from personal ambition and fear of rejection.
There are pessimists who hold that such a state of affairs is necessarily inherent in human nature; it is those who propound such views that are the enemies of true religion, for they imply thereby that religious teachings are Utopian ideals and unsuited to afford guidance in human affairs. The study of the social patterns in certain so-called primitive cultures, however, seems to have made it sufficiently evident that such a defeatist view is wholly unwarranted.

“I am often worried at the thought that my life is based to such a large extent on the work of my fellow human beings and I am aware of my great indebtedness to them.”

1930s, My Credo (1932)
Context: Our situation on this earth seems strange. Every one of us appears here involuntarily and uninvited for a short stay, without knowing the whys and the wherefore. In our daily lives we only feel that man is here for the sake of others, for those whom we love and for many other beings whose fate is connected with our own. I am often worried at the thought that my life is based to such a large extent on the work of my fellow human beings and I am aware of my great indebtedness to them.

“Our experience hitherto justifies us in trusting that nature is the realization of the simplest that is mathematically conceivable.”

from On the Method of Theoretical Physics, p. 183. The Herbert Spencer Lecture, delivered at Oxford (10 June 1933). Quoted in Einstein's Philosophy of Science http://plato.stanford.edu/entries/einstein-philscience/
1930s
Context: Our experience hitherto justifies us in trusting that nature is the realization of the simplest that is mathematically conceivable. I am convinced that purely mathematical construction enables us to find those concepts and those lawlike connections between them that provide the key to the understanding of natural phenomena. Useful mathematical concepts may well be suggested by experience, but in no way can they be derived from it. Experience naturally remains the sole criterion of the usefulness of a mathematical construction for physics. But the actual creative principle lies in mathematics. Thus, in a certain sense, I take it to be true that pure thought can grasp the real, as the ancients had dreamed.

“I agree with your remark about loving your enemy as far as actions are concerned. But for me the cognitive basis is the trust in an unrestricted causality.”

On the Christian maxim "Love thy enemy", in a letter to Michele Besso (6 January 1948)
1940s
Context: I agree with your remark about loving your enemy as far as actions are concerned. But for me the cognitive basis is the trust in an unrestricted causality. "I cannot hate him, because he must do what he does." That means for me more Spinoza than the prophets.

“This feeling mercifully mitigates the sense of responsibility which so easily becomes paralyzing, and it prevents us from taking ourselves and other people too seriously; it conduces to a view of life in which humor, above all, has its due place.”

1930s, Mein Weltbild (My World-view) (1931)
Context: In human freedom in the philosophical sense I am definitely a disbeliever. Everybody acts not only under external compulsion but also in accordance with inner necessity. Schopenhauer's saying, that "a man can do as he will, but not will as he will," has been an inspiration to me since my youth up, and a continual consolation and unfailing well-spring of patience in the face of the hardships of life, my own and others'. This feeling mercifully mitigates the sense of responsibility which so easily becomes paralyzing, and it prevents us from taking ourselves and other people too seriously; it conduces to a view of life in which humor, above all, has its due place.

“How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it.”

1930s, Mein Weltbild (My World-view) (1931)
Context: How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people — first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving....

“I regard class differences as contrary to justice and, in the last resort, based on force. I also consider that plain living is good for everybody, physically and mentally.”

1930s, Mein Weltbild (My World-view) (1931)
Context: I am strongly drawn to the simple life and am often oppressed by the feeling that I am engrossing an unnecessary amount of the labour of my fellow-men. I regard class differences as contrary to justice and, in the last resort, based on force. I also consider that plain living is good for everybody, physically and mentally.

“How does it happen that a properly endowed natural scientist comes to concern himself with epistemology?”

Obituary for physicist and philosopher Ernst Mach (Nachruf auf Ernst Mach), Physikalische Zeitschrift 17 (1916), p. 101
1910s
Context: How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there not some more valuable work to be done in his specialty? That's what I hear many of my colleagues ask, and I sense it from many more. But I cannot share this sentiment. When I think about the ablest students whom I have encountered in my teaching — that is, those who distinguish themselves by their independence of judgment and not just their quick-wittedness — I can affirm that they had a vigorous interest in epistemology. They happily began discussions about the goals and methods of science, and they showed unequivocally, through tenacious defense of their views, that the subject seemed important to them.
Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens. [Begriffe, welche sich bei der Ordnung der Dinge als nützlich erwiesen haben, erlangen über uns leicht eine solche Autorität, dass wir ihres irdischen Ursprungs vergessen und sie als unabänderliche Gegebenheiten hinnehmen. ] Thus they might come to be stamped as "necessities of thought," "a priori givens," etc. The path of scientific progress is often made impassable for a long time by such errors. [Der Weg des wissenschaftlichen Fortschritts wird durch solche Irrtümer oft für längere Zeit ungangbar gemacht. ] Therefore it is by no means an idle game if we become practiced in analysing long-held commonplace concepts and showing the circumstances on which their justification and usefulness depend, and how they have grown up, individually, out of the givens of experience. Thus their excessive authority will be broken. They will be removed if they cannot be properly legitimated, corrected if their correlation with given things be far too superfluous, or replaced if a new system can be established that we prefer for whatever reason.

“Conventional words or other signs have to be sought for laboriously only in a secondary stage, when the mentioned associative play is sufficiently established and can be reproduced at will.”

Answer to a survey written by the French mathematician Jaques Hadamard, from Hadamard's An Essay on the Psychology of Invention in the Mathematical Field (1945). Reprinted in Ideas and Opinions (1954). His full set of answers to the questions can be read on p. 3 here http://www.pitt.edu/~jdnorton/Goodies/Einstein_think/index.html.
1940s
Context: The words or the language, as they are written or spoken, do not seem to play any role in my mechanism of thought. The psychical entities which seem to serve as elements in thoughts are certain signs and more or less clear images which can be "voluntarily" reproduced and combined. There is, of course, a certain connection between those elements and relevant logical concepts. It is also clear that the desire to arrive finally at logically connected concepts is the emotional basis of this rather vague play with the above-mentioned elements.... The above-mentioned elements are, in my case, of visual and some muscular type. Conventional words or other signs have to be sought for laboriously only in a secondary stage, when the mentioned associative play is sufficiently established and can be reproduced at will.

“Even though the realms of religion and science in themselves are clearly marked off from each other, nevertheless there exist between the two strong reciprocal relationships and dependencies.”

1940s, Science and Religion (1941)
Context: Even though the realms of religion and science in themselves are clearly marked off from each other, nevertheless there exist between the two strong reciprocal relationships and dependencies. Though religion may be that which determines the goal, it has, nevertheless, learned from science, in the broadest sense, what means will contribute to the attainment of the goals it has set up. But science can only be created by those who are thoroughly imbued with the aspiration toward truth and understanding. This source of feeling, however, springs from the sphere of religion. To this there also belongs the faith in the possibility that the regulations valid for the world of existence are rational, that is, comprehensible to reason. I cannot conceive of a genuine scientist without that profound faith. The situation may be expressed by an image: science without religion is lame, religion without science is blind.
Though I have asserted above that in truth a legitimate conflict between religion and science cannot exist, I must nevertheless qualify this assertion once again on an essential point, with reference to the actual content of historical religions. This qualification has to do with the concept of God. During the youthful period of mankind's spiritual evolution human fantasy created gods in man's own image, who, by the operations of their will were supposed to determine, or at any rate to influence, the phenomenal world. Man sought to alter the disposition of these gods in his own favor by means of magic and prayer. The idea of God in the religions taught at present is a sublimation of that old concept of the gods. Its anthropomorphic character is shown, for instance, by the fact that men appeal to the Divine Being in prayers and plead for the fulfillment of their wishes.

“Religion is concerned with man's attitude toward nature at large, with the establishing of ideals for the individual and communal life, and with mutual human relationship.”

1940s, Religion and Science: Irreconcilable? (1948)
Context: Science, in the immediate, produces knowledge and, indirectly, means of action. It leads to methodical action if definite goals are set up in advance. For the function of setting up goals and passing statements of value transcends its domain. While it is true that science, to the extent of its grasp of causative connections, may reach important conclusions as to the compatibility and incompatibility of goals and evaluations, the independent and fundamental definitions regarding goals and values remain beyond science's reach.
As regards religion, on the other hand, one is generally agreed that it deals with goals and evaluations and, in general, with the emotional foundation of human thinking and acting, as far as these are not predetermined by the inalterable hereditary disposition of the human species. Religion is concerned with man's attitude toward nature at large, with the establishing of ideals for the individual and communal life, and with mutual human relationship. These ideals religion attempts to attain by exerting an educational influence on tradition and through the development and promulgation of certain easily accessible thoughts and narratives (epics and myths) which are apt to influence evaluation and action along the lines of the accepted ideals.

“Nobody, certainly, will deny that the idea of the existence of an omnipotent, just, and omnibeneficent personal God is able to accord man solace, help, and guidance; also, by virtue of its simplicity it is accessible to the most undeveloped mind. But, on the other hand, there are decisive weaknesses attached to this idea in itself, which have been painfully felt since the beginning of history.”

1940s, Science and Religion (1941)
Context: Nobody, certainly, will deny that the idea of the existence of an omnipotent, just, and omnibeneficent personal God is able to accord man solace, help, and guidance; also, by virtue of its simplicity it is accessible to the most undeveloped mind. But, on the other hand, there are decisive weaknesses attached to this idea in itself, which have been painfully felt since the beginning of history. That is, if this being is omnipotent, then every occurrence, including every human action, every human thought, and every human feeling and aspiration is also His work; how is it possible to think of holding men responsible for their deeds and thoughts before such an almighty Being? In giving out punishment and rewards He would to a certain extent be passing judgment on Himself. How can this be combined with the goodness and righteousness ascribed to Him?
The main source of the present-day conflicts between the spheres of religion and of science lies in this concept of a personal God.

“The intellect has a sharp eye for methods and tools, but is blind to ends and values.”

"The Goal of Human Existence" (1943)
1950s, Out of My Later Years (1950)
Context: And certainly we should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality. It cannot lead, it can only serve; and it is not fastidious in its choice of a leader. This characteristic is reflected in the qualities of its priests, the intellectuals. The intellect has a sharp eye for methods and tools, but is blind to ends and values. So it is no wonder that this fatal blindness is handed on from old to young and today involves a whole generation.

“We followers of Spinoza see our God in the wonderful order and lawfulness of all that exists and in its soul ("Beseeltheit") as it reveals itself in man and animal.”

From a letter to Eduard Büsching (25 October 1929) after Büsching sent Einstein a copy of his book Es gibt keinen Gott [There Is no God]. Einstein responded that the book only dealt with the concept of a personal God, p. 51
Attributed in posthumous publications, Einstein and Religion (1999)
Context: We followers of Spinoza see our God in the wonderful order and lawfulness of all that exists and in its soul ("Beseeltheit") as it reveals itself in man and animal. It is a different question whether belief in a personal God should be contested. Freud endorsed this view in his latest publication. I myself would never engage in such a task. For such a belief seems to me preferable to the lack of any transcendental outlook of life, and I wonder whether one can ever successfully render to the majority of mankind a more sublime means in order to satisfy its metaphysical needs.

“Standardization robs life of its spice.”

1920s, Viereck interview (1929)
Context: But to return to the Jewish question. Other groups and nations cultivate their individual traditions. There is no reason why we should sacrifice ours. Standardization robs life of its spice. To deprive every ethnic group of its special traditions is to convert the world into a huge Ford plant. I believe in standardizing automobiles. I do not believe in standardizing human beings. Standardization is a great peril which threatens American culture.

“The fact that it is comprehensible is a miracle.”

"Physics and Reality" (1936), p. 61 http://books.google.com/books?id=Q1UxYzuI2oQC&lpg=PP1&pg=PA61#v=onepage&q&f=false
1950s, Out of My Later Years (1950)
Context: The very fact that the totality of our sense experience is such that by means of thinking (operations with concepts, and the creation and use of definite functional relations between them, and the coordination of sense experience to these concepts) it can be put in order, this fact is one which leaves us in awe, but which we shall never understand. One may say "the eternal mystery of the world is its comprehensibility."... In speaking here concerning "comprehensibility," the expression is used in its most modest sense. It implies: the production of some sort of order among sense impressions, this order being produced by the creation of general concepts, relations between these concepts, and by relations between the concepts and sense experience, these relations being determined in any possible manner. It is in this sense that the world of our sense experience is comprehensible. The fact that it is comprehensible is a miracle.

“I have repeatedly said that in my opinion the idea of a personal God is a childlike one.”

Letter to Guy H. Raner Jr. (28 September 1949), from article by Michael R. Gilmore in Skeptic magazine, Vol. 5, No. 2 (1997)
1940s
Context: I have repeatedly said that in my opinion the idea of a personal God is a childlike one. You may call me an agnostic, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being.
