Pour un être conscient, exister consiste à changer, changer à se mûrir, se mûrir à se créer indéfiniment soi-même. - Henri Bergson

Thus I repudiate facility. I recommend a certain manner of thinking which courts difficulty; I value effort above everything. How could certain people have mistaken my meaning? To say nothing of the kind of person who would insist that my “intuition” was instinct or feeling. Not one line of what I have written could lend itself to such an interpretation. And in everything I have written there is assurance to the contrary: my intuition is reflection. But because I called attention to the mobility at the base of things, it has been claimed that I encouraged a sort of relaxing of the mind. And because the permanence of substance was, in my eyes, a continuity of change, it has been said that my doctrine was a justification of instability. One might just as well imagine that the bacteriologist recommends microbic diseases to us when he shows us microbes everywhere, or that the physicist prescribes the exercise of swinging when he reduces natural phenomena to oscillations. A principle of explanation is one thing, a maxim of conduct is another. One could almost say that the philosopher who finds mobility everywhere is the only one who cannot recommend it, since he sees it as inevitable, since he discovers it in what people have agreed to call immobility. But the truth is that in spite of the fact that he views stability as a complexity of change or as a particular aspect of change, in spite of the fact that in some way he resolves stability into change he will none the less, like everybody else, distinguish stability and change. And for him, as for everyone, will arise the question of knowing to what extent it is the special appearance called stability, to what extent it is change pure and simple that he must recommend to human societies. His analysis of change leaves this question intact. If he has any common sense at all, he, like everyone else, will consider necessary a permanence of what is. He will say that institutions should furnish a relatively invariable framework

Long before being artists, we are artisans; and all fabrication, however rudimentary, lives on likeness and repetition, like the natural geometry which serves as its fulcrum. Fabrication works on models which it sets out to reproduce; and even when it invents, it proceeds, or imagines itself to proceed, by a new arrangement of elements already known. Its principle is that “we must have like to produce like.” In short, the strict application of the principle of finality, like that of the principle of mechanical causality, leads to the conclusion that “all is given.” Both principles say the same thing in their respective languages, because they respond to the same need.

I cannot escape the objection that there is no state of mind, however simple, that does not change every moment.
