One does well to put on gloves when reading the New Testament. The proximity of so much uncleanliness almost forces one to do this.

Body am I entirely, and nothing else; and soul is only a word for something about the body.

Spirit is the life that itself cuts into life: with its own torment it increases its own knowledge. Did you already know that?

We cannot even reproduce our thoughts entirely in words.

When an idea is just rising on the horizon, the soul's temperature with respect to it is usually very cold. Only gradually does the idea develop its warmth, and it is hottest (which is to say, exerting its greatest influence) when belief in the idea is already once again in decline.

He who cannot obey himself will be commanded. That is the nature of living creatures.
