“Art is about collecting experiences and expressing them. For me music and photography are similar art forms. I collect experiences, stir them in myself and express it in my own language. Just like my photography, music is my language.”

“Love is a joint experience between two persons -- but the fact that it is a joint experience does not mean that it is a similar experience to the two people involved.”

“In a certain sense all knowledge is inductive. We can only learn the laws and relations of things in nature by observing those things. But the knowledge gained from the senses is knowledge only of particular facts, and we require some process of reasoning by which we may collect out of the facts the laws obeyed by them. Experience gives us the materials of knowledge: induction digests those materials, and yields us general knowledge. When we possess such knowledge, in the form of general propositions and natural laws, we can usefully apply the reverse process of deduction to ascertain the exact information required at any moment. In its ultimate foundation, then, all knowledge is inductive—in the sense that it is derived by a certain inductive reasoning from the facts of experience.”

“To conceive of knowledge as a collection of information seems to rob the concept of all of its life. Knowledge resides in the user and not in the collection. It is how the user reacts to a collection of information that matters.”

“The fact that these principles, collected from the writings of half a dozen different people, many of whom made no attempt to correlate their work with others, can be presented in a coherent and logical pattern is in itself strong evidence that there is a common element in all experience of the conduct of social groups, that a true science of administration is ultimately possible.”

“Now, it is unquestionable that language, and consequently the system of concepts which it translates, is the product of a collective elaboration. What it expresses is the manner in which society as a whole represents the facts of experience. The ideas which correspond to the diverse elements of language are thus collective representations. Even their contents bear witness to the same fact. In fact, there are scarcely any words among those which we usually employ whose meaning does not pass, to a greater or less extent, the limits of our personal experience. Very frequently a term expresses things which we have never perceived or experiences which we have never had or of which we have never been the witness. Even when we know some of the objects which it concerns, it is only as particular examples that serve to illustrate the idea which they would never have been able to form by themselves. Thus there is a great deal of knowledge condensed in the word which I never collected, and which is not individual; it even surpasses me to such an extent that I cannot even completely appropriate all its results. Which of us knows all the words of the language he speaks and the entire signification of each?”

“Collect all the facts that can be collected about the life of Racine and you will never learn from them the art of his verse.”

Paul Valéry (1871–1945) French poet, essayist, and philosopher

Introduction to the Method of Leonardo da Vinci (1895)
Context: Collect all the facts that can be collected about the life of Racine and you will never learn from them the art of his verse. All criticism is dominated by the outworn theory that the man is the cause of the work as in the eyes of the law the criminal is the cause of the crime. Far rather are they both the effects.

“In a true and perfect form, imperturbability is indissolubly associated with wide experience and an intimate knowledge of the varied aspects of disease.”

William Osler (1849–1919) Canadian pathologist, physician, educator, bibliophile, historian, author, cofounder of Johns Hopkins Hospi…

Aequanimitas (1889)
Context: In a true and perfect form, imperturbability is indissolubly associated with wide experience and an intimate knowledge of the varied aspects of disease. With such advantages he is so equipped that no eventuality can disturb the mental equilibrium of the physician; the possibilities are always manifest, and the course of action clear. From its very nature this precious quality is liable to be misinterpreted, and the general accusation of hardness, so often brought against the profession, has here its foundation. Now a certain measure of insensibility is not only an advantage, but a positive necessity in the exercise of a calm judgment, and in carrying out delicate operations. Keen sensibility is doubtless a virtue of high order, when it does not interfere with steadiness of hand or coolness of nerve; but for the practitioner in his working-day world, a callousness which thinks only of the good to be effected, and goes ahead regardless of smaller considerations, is the preferable quality.
Cultivate, then, gentlemen, such a judicious measure of obtuseness as will enable you to meet the exigencies of practice with firmness and courage, without, at the same time, hardening "the human heart by which we live."

“Mistakes are painful when they happen, but years later a collection of mistakes is what is called experience.”
