Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.
If a person is stupid, we excuse him by saying that he cannot help it; but if we attempted to excuse in precisely the same way the person who is bad, we should be laughed at.
Animals learn death first at the moment of death;...man approaches death with the knowledge it is closer every hour, and this creates a feeling of uncertainty over his life, even for him who forgets in the business of life that annihilation is awaiting him.
