"Mais, si le souvenir n'a pas été emmagasiné par le cerveau, où donc se conserve-t-il ? - A vrai dire, je ne suis pas sûr que la question "où" ait en… - Henri Bergson

The general intelligence which is the faculty of arranging concepts “reasonably” and handling words suitably, must therefore aid in the social life just as intelligence in the narrower sense of the word, which is the mathematical function of the mind, presides over the knowledge of matter. It is the first of these we have in mind when we say of a man that he is intelligent. By that we mean that he has the ability and the facility for combining the ordinary concepts and for drawing probable conclusions from them. One can hardly take issue with him on that account, as long as he confines himself to things of every-day life, for which the concepts were made. But one would hardly admit of a man who was merely intelligent undertaking to speak with authority on scientific questions seeing that the intellect, made precise in science, becomes a mathematical, physical and biological attitude of mind, and substitutes for words more appropriate signs. All the more should one forbid him to meddle in philosophy when the questions raised are no longer in the domain of the intelligence alone. But no, it is agreed that the intelligent man is on this point a competent man. Against this I protest most vigorously. I hold the intelligence in high esteem, but I have a very mediocre opinion of the “intelligent man,” whose cleverness consists in talking about all things with a show of truth.

Je dirais qu'il faut agir en homme de pensée et penser en homme d'action.

Useful professions are clearly meant for the public, but those whose utility is more dubious can only justify their existence by assuming that the public is meant for them.
