Knowledge of the soul is the only universal truth and the only wisdom - all other knowledge is transient.
Seek truth while you are young, for if you do not, it will later escape your grasp.
A library of wisdom, is more precious than all wealth, and all things that are desirable cannot be compared to it. Whoever therefore claims to be zealous of truth, of happiness, of wisdom or knowledge, must become a lover of books.
The true lover of knowledge naturally strives for truth, and is not content with common opinion, but soars with undimmed and unwearied passion till he grasps the essential nature of things.
The philosopher is in love with truth, that is, not with the changing world of sensation, which is the object of opinion, but with the unchanging reality which is the object of knowledge.
The souls of people, on their way to Earth-life, pass through a room full of lights; each takes a taper - often only a spark - to guide it in the dim country of this world. But some souls, by rare fortune, are detained longer - have time to grasp a handful of tapers, which they weave into a torch. These are the torch-bearers of humanity - its poets, seers and saints, who lead and lift the race out of darkness, toward the light. They are the law-givers and saviors, the light-bringers, way-showers and truth-tellers, and without them, humanity would lose its way in the dark.
There is nothing so delightful as the hearing, or the speaking of truth. For this reason, there is no conversation so agreeable as that of the man of integrity, who hears without any intention to betray, and speaks without any intention to deceive.
