"Nothing is more conducive to peace of mind than not having any opinion at all." — Georg C. Lichtenberg

That man is the noblest creature may also be inferred from the fact that no other creature has yet contested this claim.

A book is a mirror: if an ape looks into it an apostle is hardly likely to look out.

Virtue by premeditation isn't worth much.

Nothing can contribute more to peace of soul than the lack of any opinion whatever.
