But man acquires skill only by observation and experiment. He reflects, then, since to observe and experiment is to reflect; he reasons, since he cannot help reasoning. In reflecting, he becomes deluded; in reasoning, he makes mistakes, and, thinking himself right, persists in them. He is wedded to his opinions; he esteems himself, and despises others. Consequently, he isolates himself; for he could not submit to the majority without renouncing his will and his reason,--that is, without disowning himself, which is impossible. And this isolation, this intellectual egotism, this individuality of opinion, lasts until the truth is demonstrated to him by observation and experience. A final illustration will make these facts still clearer. If to the blind but convergent and harmonious instincts of a swarm of bees should be suddenly added reflection and judgment, the little society could not long exist. In the first place, the bees would not fail to try some new industrial process; for instance, that of making their cells round or square. All sorts of systems and inventions would be tried, until long experience, aided by geometry, should show them that the hexagonal shape is the best. Then insurrections would occur. The drones would be told to provide for themselves, and the queens to labor; jealousy would spread among the laborers; discords would burst forth; soon each one would want to produce on his own account; and finally the hive would be abandoned, and the bees would perish. Evil would be introduced into the honey-producing republic by the power of reflection,--the very faculty which ought to constitute its glory.
