So much are our minds influenced by the accidents of our bodies, that every man is more the man of the day than a regular and consequential character.

The flesh believes that pleasure is limitless and that it requires unlimited time; but the mind, understanding the end and limit of the flesh and ridding itself of fears of the future, secures a complete life and has no longer any need for unlimited time.

The flesh endures the storms of the present alone, the mind those of the past and future as well as the present.

At three o'clock in the morning, a forgotten package has the same tragic importance as a death sentence, and the cure doesn't work-and in a real dark night of the soul it is always three o'clock in the morning, day after day.

Man is a mind betrayed, not served, by his organs.

What we think and feel and are is to a great extent determined by the state of our ductless glands and our viscera.

Just make someone who has fallen in love listen to his stomach rumble, and the unity of body and soul, that lyrical illusion of the age of science, instantly falls away.

If the mind, which rules the body, ever forgets itself so far as to trample upon its slave, the slave is never generous enough to forgive the injury; but will rise and smite its oppressor.

Man is to himself the most wonderful object in nature; for he cannot conceive what the body is, still less what the mind is, and least of all how a body should be united to a mind.

All the soarings of my mind begin in my blood.
