Learning is by nature, curiosity.

The body is the soul's house. Shouldn't we therefore take care of our house so that it doesn't fall into ruin?

The air is full of souls those who are nearest to earth descending to be tied to mortal bodies return to other bodies, desiring to live in them.

I know that God exists. I know that I have never invented anything. I have been a medium by which these things were given to the culture as fast as the culture could earn them. I give all the credit to God.

Remorse for what is done is useless.

Households, cities, countries and nations have enjoyed great happiness, when a single individual has taken heed of the Good and Beautiful. Such men not only liberate themselves; they fill those they meet with a free mind.

Learning is by nature curiosity... prying into everything, reluctant to leave anything, material or immaterial, unexplained.
