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.
Seneca the YoungerWe are more easily led part by part to an understanding of the whole. -Facilius per partes in cognitionem totius adducimur
