Properly to live, not to lose a heart? For what does a man need philosophy? What is a difference in between philosophy and mathematics? That brings to us the greatest troubles? How to correct the life?Collection was entered by the select "Moral letters to Луцилию", tragedies of "Медея", "Федра", "Oedipus", "Фиэст", "Агамемнон" and "Октавия" and philosophical treatise "About happy life".In the format of a4.pdf is stored publishing layout.
