The soul must have its chosen sewers to carry away its ordure. This function is performed by persons, relationships, professions, the fatherland, the world, or finally, for the really arrogant - I mean our modern pessimists - by the Good God himself.
If we affirm one moment, we thus affirm not only ourselves but all existence. For nothing is self-sufficient, neither in us ourselves nor in things; and if our soul has trembled with happiness and sounded like a harp string just once, all eternity was needed to produce this one event - and in this single moment of affirmation all eternity was called good, redeemed, justified, and affirmed.
If you spend too much time trying to find out what is good or bad about someone else, you'll forget your own soul and end up exhausted and defeated by the energy you have wasted in judging others.
The soul has two parts, one rational and the other irrational. Let us now similarly divide the rational part, and let it be assumed that there are two rational faculties, one whereby we contemplate those things whose first principles are invariable, and one whereby we contemplate those things which admit of variation.
The soul is the cause or source of the living body. The terms cause and source have many senses. But the soul is the cause of its body alike in all three senses which we explicitly recognize. It is (a) the source or origin of movement, it is (b) the end, it is (c) the essence of the whole living body.
