You will never be an inwardly religious and devout man unless you pass over in silence the shortcomings of your fellow men, and diligently examine your own weaknesses.

... we know what we are, but know not what we may be.

Nothing will make us so charitable and tender to the faults of others, as, by self-examination, thoroughly to know our own.

Go to your bosom; Knock there, and ask your heart what it doth know ...

The examined life is no picnic.

The unexamined life is not worth living.

O wad some power the giftie gie us, To see ourselves as others see us!

Know then thyself, presume not God to scan; The proper study of mankind is man.

Learn what you are and be such.
