The best Armour of Old Age is a well spent life preceding it; a Life employed in the Pursuit of useful Knowledge, in honourable Actions and the Practice of Virtue; in which he who labours to improve himself from his Youth, will in Age reap the happiest Fruits of them; not only because these never leave a Man, not even in the extremest Old Age; but because a Conscience bearing Witness that our Life was well-spent, together with the Remembrance of past good Actions, yields an unspeakable Comfort to the Soul

A happy life consists in tranquility of mind.

Justice renders to every one his due.

Nothing is more noble, nothing more venerable than fidelity. Faithfulness and truth are the most sacred excellences and endowments of the human mind.

While all other things are uncertain, evanescent, and ephemeral, virtue alone is fixed with deep roots; it can neither be overthrown by any violence or moved from its place.

Nothing stands out so conspicuously, or remains so firmly fixed in the memory, as something which you have blundered.

Six mistakes mankind keeps making century after century: Believing that personal gain is made by crushing others; Worrying about things that cannot be changed or corrected; Insisting that a thing is impossible because we cannot accomplish it; Refusing to set aside trivial preferences; Neglecting development and refinement of the mind; Attempting to compel others to believe and live as we do.
