We are never the same with others as when we are alone. We are different, even when we are in the dark with them.
We possess only the happiness we are able to understand.
Happiness is rarely absent; it is we that know not of its presence.
All our knowledge merely helps us to die a more painful death than animals that know nothing.
Our reason may prove what it will: our reason is only a feeble ray that has issued from Nature.
A truth that disheartens because it is true is of more value than the most stimulating of falsehoods.
