“Human nature is so constituted that the propensity for evil is always intensified by external circumstances, and the morality of the individual depends much more on the conditions of his existence and the environment in which he lives than on his own will. ”

“Habit is a compromise effected between the individual and his environment, or between the individual and his own organic eccentricities, the guarantee of a dull inviolability, the lightning-conductor of his existence.”

“The first theft marked Buck as fit to survive in the hostile Northland environment. It marked his adaptability, his capacity to adjust himself to changing conditions, the lack of which would have meant swift and terrible death. It marked, further, the decay or going to pieces of his moral nature, a vain thing and a handicap in the ruthless struggle for existence.”

“No one is accountable for existing at all, or for being constituted as he is, or for living in the circumstances and surroundings in which he lives. The fatality of his nature cannot be disentangled from the fatality of all that which has been and will be. He is not the result of a special design, a will, a purpose; he is not the subject of an attempt to attain an 'ideal of man' or an 'ideal of happiness' or an 'ideal of morality'--it is absurd to want to hand over his nature to some purpose or other. We invented the concept 'purpose': in reality purpose is lacking...One is necessary, one is a piece of fate, one belongs to the whole, one is in the whole--there exists nothing which could judge, measure, compare, condemn our being, for that would be to judge, measure, condemn the whole...”

“Indeed, compulsive and rigid moralism arises in given persons precisely as the result of a lack of sense of being. Rigid moralism is a compensatory mechanism by which the individual persuades himself to take over the external sanctions because he has no fundamental assurance that his own choices have any sanction of their own”

“By the grace of reality and the nature of life, man–every man–is an end in himself, he exists for his own sake, and the achievement of his own happiness is his highest moral purpose”
