Bloody revolutions are often necessary, thanks to human stupidity; yet they are always an evil, a monstrous evil and a great disaster, not only with … - Mikhail Bakunin

"Does it follow that I reject all authority? Perish the thought. In the matter of boots, I defer to the authority of the bootmaker; concerning houses, canals, or railroads, I consult the architect or the engineer For such special knowledge I apply to such a "savant." But I allow neither the bootmaker nor the architect nor the "savant" to impose his authority on me. I listen to them freely and with all the respect merited by their intelligence, their character, their knowledge, reserving always my incontestable right of criticism and censure. I do not content myself with consulting a single authority in any special branch; I consult several; I compare their opinions and choose that which seems to me soundest. But I recognize no infallible authority, even m special questions; consequently, whatever respect I may have for the honesty and the sincerity of an individual, I have no absolute faith in any person. Such a faith would be fatal to my reason, to my liberty, and even to the success of my undertakings; it would immediately transform me into a stupid slave, the tool of other people's will and interests."

The general idea is always an abstraction and, for that very reason, in some sort a negation of real life. And every time that scientific men, emerging from their abstract world, mingle with living creation in the real world, all that they propose or create is poor, ridiculously abstract, bloodless and lifeless, still-born, like the homunculus created by Wagner, the pedantic disciple of the immortal Doctor Faust.

Muy otro es el punto de vista de los idealistas. En su sistema, el hombre se produce primeramente como un ser inmortal y libre y acaba por convertirse en un esclavo.
