I love the broad margin to my life.

The man who thrusts his manners upon me does as if he were to insist on introducing me to his cabinet of curiosities, when I wished to see himself.

It is far more independent to travel on foot. You have to sacrifice so much to the horse. You cannot choose the most agreeable places in which to spend the noon., commanding the finest views, because commonly there is no water there, or you cannot get there with your horse.

But perhaps a man is not required to bury himself.

My desire for knowledge is intermittent; but my desire to commune with the spirit of the universe, to be intoxicated with the fumes, call it, of that divine nectar, to bear my head through atmospheres and over heights unknown to my feet, is perennial and constant.

Nothing is so much to be feared as fear.

A person who chooses to die or to risk death demonstrates that there are values, principles, maxims, that are more valuable to him than is life itself. In short, he places his immortal self above his mortal self. Nothing goes by luck in composition. It allows of no tricks. The best you can write will be the best you are.
