Leo Tolstoy’s theory of everything - Salon.com: "It was Augustine, in the celebrated Book 11 of the Confessions, who first expressed his bewilderment: “What is time?” He argued as follows: The future is not yet here, the past is no longer here, and the present does not remain. Does time, then, have a real being? What is the present? The day? But “not even one day is entirely present.” Some hours of the day are in the future, some in the past. The hour? But “one hour is itself constituted of fugitive moments.”"
Tolstoy asks perennial philosophical questions.
