Humanity is moving in a circle. The progress in mechanical things of the past hundred years has proceeded at the cost of losing many other things which perhaps were much more important for it.

Knowledge by itself does not give understanding. Nor is understanding increased by an increase of knowledge alone. Understanding depends upon the relation of knowledge to being...It appears only when a man feels and senses what is connected with it.

As long as our ideas are the same, we will never be apart.

In order to understand the interrelation of truth and falsehood in life, a man must understand falsehood in himself, the constant incessant lies he tells himself.

By teaching others you will learn yourself.

Without struggle, no progress and no result. Every breaking of habit produces a change in the machine.

Man has no individual 'I'. But there are, instead, hundreds and thousands of separate small 'I's, very often entirely unknown to one another, never coming into contact, or, on the contrary, hostile to each other, mutually exclusive and incompatible. Each minute, each moment, man is saying or thinking, 'I'. And each time his 'I' is different. Just now it was a thought, now it is a desire, now a sensation, now another thought, and so on, endlessly. Man is a plurality. Man's name is legion.
