“This is the seat of the experience that life is a mixture of good and evil; that there is no such thing as pure good; and that if the evil weren’t there as a potentiality, the good would not be either. Life consists of achieving good not apart from evil but in spite of it.”
“In psychology, power means the ability to affect, to influence, and to change other persons. Each person exists in an interpersonal web, analogous to magnetic fields of force; and each one propels, repels, connects, identifies with others.”
I estimate the power of a will according to how much resistance, pain and torture it endures and knows how to transform to its own advantage. – Nietzsche
