Having seen that I was not capable of using all my resources in political action, I returned to my literary activity. There lay the the battlefield suited to my temperament. I wanted to make my novels the extension of my own father's struggle for liberty. But gradually, as I kept deepening my responsibility as a writer, the human problem came to overshadow political and social questions. All the political, social, and economic improvements, all the technical progress cannot have any regenerating significance, so long as our inner life remains as it is at present. The more the intelligence unveils and violates the secrets of Nature, the more the danger increases and the heart shrinks.

As quoted in Nikos Kazantzakis (1968) by Helen Kazantzakis, p. 529
