Vain is the word of a philosopher which does not heal any suffering of man. For just as there is no profit in medicine if it does not expel the diseases of the body, so there is no profit in philosophy either, if it does not expel the suffering of the mind.
Luxurious food and drinks, in no way protect you from harm. Wealth beyond what is natural, is no more use than an overflowing container. Real value is not generated by theaters, and baths, perfumes or ointments, but by philosophy.
He who says either that the time for philosophy has not yet come or that it has passed is like someone who says that the time for happiness has not yet come or that it has passed.
Let no one delay the study of philosophy while young nor weary of it when old.
Let no young man delay the study of philosophy, and let no old man become weary of it; for it is never too early nor too late to care for the well-being of the soul.
Neither one should hesitate about dedicating oneself to philosophy when young, nor should get tired of doing it when one's old, because no one is ever too young or too old to reach one's soul's healthy.
All other love is extinguished by self-love; beneficence, humanity, justice, philosophy, sink under it.
If you would enjoy real freedom, you must be the slave of Philosophy.
