O maior inimigo do riso é a emoção. - Henri Bergson

In a society composed of pure intelligences there would probably be no more tears, though perhaps there would still be laughter; whereas highly emotional souls, in tune and unison with life, in whom every event would be sentimentally prolonged and re-echoed, would neither know nor understand laughter.

The question is precisely to know whether the past has ceased to exist, or ceased to be useful...

One could say as much for perception. The auxiliary of action, it isolates that part of reality as a whole that interests us; it shows us less the things themselves than the use we can make of them. It classifies, it labels them beforehand; we scarcely look at the object, it is enough for us to know to which category it belongs. But now and then, by a lucky accident, men arise whose senses or whose consciousness are less adherent to life. Nature has forgotten to attach their faculty of perceiving to their faculty of acting. When they look at a thing, they see it for itself, and not for themselves. They do not perceive simply with a view to action; they perceive in order to perceive, — for nothing, for the pleasure of doing so.
