Instruction and education have no age. The philiawisdomethics science is a method permitting to search the arts of good life. The principle of philosophical action, of philosophical arts, reside in an analytical mind, of wondering, either of question, contrary to all acquired sciences. The philosopher does not make himself a connoisseur, but as a human being that wants to know something very well. To avoid falling in believes that have no issue, illusions and appearances, he use reason or intellect. To know himself better, he does not search truth by someone else, but through himself. To uninitiated, philosophical science is an unimportant subject, and the philosopher a schizophrener. Those that hate the philosophical arts, consider it as a simple abstract reflexion, which has no link with the visible life. From the moment that philosophy requires to situate oneself out of the world, before all self exteriorisation, it is as such a way to deny life. The real philosopher has no other interest than to learn how to get out of the world, and to live as he is not in the world, according to Emperoy. Legends, anecdotes, on anti-philosophers show that they were persons living out of the Marge of reality.
