Life without literary studies is death.

A good conscience fears no witness, but a guilty conscience is solicitous even in solitude. If we do nothing but what is honest, let all the world know it. But if otherwise, what does it signify to have nobody else know it, so long as I know it myself? Miserable is he who slights that witness.
