Outline of the Doctrine of Knowledge (1810)
Context: There is but One Principle that proceeds from God; and thus, in consequence of the unity of the Power, it is possible for each Individual to schematise his World of Sense in accordance with the law of that original harmony; — and every Individual, under the condition of being found on the way towards the recognition of the Imperative, must so schematise it. I might say: — Every Individual can and must, under the given condition, construct the True World of Sense, — for this indeed has beyond the universal and formal laws above deduced, no other Truth and Reality than this universal harmony.

Dedication to Emma Goldman
Context: Now my education, life and consciousness are talked about by those who cannot understand what I wrote, what I think, what is my life. They make me up from their subjective imagination and attack me publicly as well as secretly. Because my novels completely obscure my behaviour and ideas, and result in a lot of misunderstandings, my name is related to nihilism or humanism, although I have written a book of over three hundred pages to explain my ideas (this book is very easy to understand and without a metaphysical term). Those who talk about me never read it. They judged my ideas according to one of my short stories, then deduced a variety of strange conclusions and decided which doctrine I belong to. I have been caught in this predicament all these years and cannot get rid of it...

Preface
The History and Present State of Electricity (1767)
Context: The History of Electricity is a field full of pleasing objects, according to all the genuine and universal principles of taste, deduced from a knowledge of human nature. Scenes like these, in which we see a gradual rise and progress in things, always exhibit a pleasing spectacle to the human mind. Nature, in all her delightful walks, abounds with such views, and they are in a more especial manner connected with every thing that relates to human life and happiness; things, in their own nature, the most interesting to us. Hence it is, that the power of association has annexed crowds of pleasing sensations to the contemplation of every object, in which this property is apparent.
This pleasure, likewise, bears a considerable resemblance to that of the sublime, which is one of the most exquisite of all those that affect the human imagination. For an object in which we see a perpetual progress and improvement is, as it were, continually rising in its magnitude; and moreover, when we see an actual increase, in a long period of time past, we cannot help forming an idea of an unlimited increase in futurity; which is a prospect really boundless, and sublime.

Introduction
A Treatise of Human Nature (1739-40)
Context: Nothing is more usual and more natural for those, who pretend to discover anything new to the world in philosophy and the sciences, than to insinuate the praises of their own systems, by decrying all those, which have been advanced before them. And indeed were they content with lamenting that ignorance, which we still lie under in the most important questions, that can come before the tribunal of human reason, there are few, who have an acquaintance with the sciences, that would not readily agree with them. 'Tis easy for one of judgment and learning, to perceive the weak foundation even of those systems, which have obtained the greatest credit, and have carried their pretensions highest to accurate and profound reasoning. Principles taken upon trust, consequences lamely deduced from them, want of coherence in the parts, and of evidence in the whole, these are every where to be met with in the systems of the most eminent philosophers, and seem to have drawn disgrace upon philosophy itself.

The Federalist Papers (1787–1788)
Context: There is yet a further and a weightier reason for the permanency of the Judicial offices, which is deducible from the nature of the qualifications they require. It has been frequently remarked, with great propriety, that a voluminous code of laws is one of the inconveniences necessarily connected with the advantages of a free Government. To avoid an arbitrary discretion in the Courts, it is indispensable that they should be bound down by strict rules and precedents, which serve to define and point out their duty in every particular case that comes before them; and it will readily be conceived from the variety of controversies which grow out of the folly and wickedness of mankind, that the records of those precedents must unavoidably swell to a very considerable bulk, and must demand long and laborious study to acquire a competent knowledge of them. Hence it is, that there can be but few men in the society, who will have sufficient skill in the laws to qualify them for the stations of Judges. And making the proper deductions for the ordinary depravity of human nature, the number must be still smaller of those who unite the requisite integrity with the requisite knowledge. These considerations apprize us, that the Government can have no great option between fit characters; and that a temporary duration in office, which would naturally discourage such characters from quitting a lucrative line of practice to accept a seat on the Bench, would have a tendency to throw the administration of justice into hands less able, and less well qualified, to conduct it with utility and dignity.

Section 9 : Ethical Outlook
Founding Address (1876), Life and Destiny (1913)
Context: Theologians often say that faith must come first, and that morality must be deduced from faith. We say that morality must come first, and faith, to those whose nature fits them to entertain it, will come out of the experience of a deepened moral life as its richest, choicest fruit.
Precisely because moral culture is the aim, we cannot be content merely to lift the mass of mankind above the grosser forms of evil. We must try to advance the cause of humanity by developing in ourselves, as well as in others, a higher type of manhood and womanhood than the past has known.
To aid in the evolution of a new conscience, to inject living streams of moral force into the dry veins of materialistic communities is our aim.
We seek to come into touch with the ultimate power in things, the ultimate peace in things, which yet, in any literal sense, we know well that we cannot know. We seek to become morally certain — that is, certain for moral purposes — of what is beyond the reach of demonstration. But our moral optimism must include the darkest facts that pessimism can point to, include them and transcend them.

Context: Fermat knew that under reflection light takes the path requiring least time and, convinced that nature does indeed act simply and economically, affirmed in letters of 1657 and 1662 his Principle of Least Time, which states that light always takes the path requiring least time. He had doubted the correctness of the law of refraction of light but when he found in 1661 that he could deduce it from his Principle, he not only resolved his doubts about the law but felt all the more certain that his Principle was correct.... Huygens, who had at first objected to Fermat's Principle, showed that it does hold for the propagation of light in media with variable indices of refraction. Even Newton's first law of motion, which states that the straight line or shortest distance is the natural motion of a body, showed nature's desire to economize. These examples suggested that there might be a more general principle. The search for such a principle was undertaken by Maupertuis.
