Obstacles cannot crush me. Every obstacle yields to stern resolve. He who is fixed to a star does not change his mind.

The length of a man's outspread arms is equal to his height.

Just as eating against one's will is injurious to health, so studying without a liking for it spoils the memory, and it retains nothing it takes in.

Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.

I roamed the countryside searching for answers to things I did not understand.

Nothing will be left, Nothing in the air, nothing under the earth, nothing in the waters. All will be exterminated.

Not to appreciate life, all of life, is not to deserve it.
