Your chemistry high school teacher lied to you when they told you that there was such a thing as a vacuum, that you could take space and move every particle out of it.
Find a teacher who is an integral being, a beacon who extends his light and virtue with equal ease to those who appreciate him and those who don't. Shape yourself in his mold, bathe in his nourishing radiance, and reflect it out to the rest of the world.
The self taught man seldom knows anything accurately, and he does not know a tenth as much as he could have known if he had worked under teachers, and besides, he brags, and is the means of fooling other thoughtless people into going and doing as he himself has done.
The market system rewards me outlandishly for what I do, but that doesn't mean I'm any more deserving of a good life than a teacher or a doctor or someone who fights in Afghanistan.
The purpose of having the title 'World-Teacher' is to acknowledge, to show, the condition of mind and heart when you have achieved. It is like saying: 'I have painted a picture'. It is like saying: 'I have written a poem'. It is an assertion of the fact of attainment, rather than the narrow understanding that is given to labels and phrases. What the phrase indicates is of importance.
Just what should a young man or woman know to be 'in the know'? Is there, in other words, some inside information, some special taboo, some real lowdown on life and existence that most parents and teachers either don't know or won't tell?
Education of youth is not a bow for every man to shoot in that counts himself a teacher; but will require sinews almost equal to those which Homer gave to Ulysses.
Now know I well what people sought formerly above all else when they sought Teachers of virtue. Good sleep they sought for themselves, and poppy-head virtues to promote it! To all those be-lauded sages of the academic chairs, wisdom was sleep Without dreams: they knew no higher significance of life. Even at present, to be sure, there are some like this preacher of virtue, and not always so honorable: but their time is past. And not much longer do they stand: there they already lie. Blessed are those drowsy ones: for they shall soon nod to sleep.-Thus spoke Zarathustra.
The good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.
