How often does a man ruin his disciples by remaining always with them! When men are once trained, it is essential that their leader leave them, for without his absence they cannot develop themselves. Plants always remain small under a big tree.
The value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it. Indeed, the probabilities are that the more insincere the man is, the more purely intellectual will the idea be, as in that case it will not be coloured by either his wants, his desires, or his prejudices.
The Idols of Tribe have their foundation in human nature itself, and in the tribe or race of men. For it is a false assertion that the sense of man is the measure of things. On the contrary, all perceptions as well of the sense as of the mind are according to the measure of the individual and not according to the measure of the universe. And the human understanding is like a false mirror, which, receiving rays irregularly, distorts and discolors the nature of things by mingling its own nature with it.
Wealth and honours, which most men pursue, easily change masters; they desert to the side which excels in virtue, industry, and endurance of toil, and they abandon the slothful.
You'll see all other mortal sinners, the ones who flout the honor owed to gods or guests, or loving parents--you'll see them get the justice they deserve. For Hades holds men mightily to a strict accounting down below the earth; he sees all things, inscribes them within the book of his remembering.
Verily, a polluted stream is man. One must actually be a sea to take in a polluted stream without becoming impure. Behold, I teach you the superman: he is the this sea, in him can your great contempt go under.
Man has received direct from God only one instrument wherewith to know himself and to know his relation to the universe--he has no other--and that instrument is reason.
It is an unfortunate fact that every man who seeks to disseminate knowledge must contend not only against ignorance itself, but against false instruction as well. No sooner do we deem ourselves free from a particularly gross superstition, than we are confronted by some enemy to learning who would set aside all the intellectual progress of years, and plunge us back into the darkness of mediaeval disbelief.
'But surely "blind" is just how you would describe men who have no true knowledge of reality, and no clear standard in their mind to refer to, as a painter refers to his model, and which they can study closely before they start laying down rules about what is fair or right or good where they are needed, or maintaining, as Guardians, any rules that already exist.'
'Yes, blind is just about what they are'
