Maybe no great man is virtuous. Or good. Perhaps a man rich in those qualities by definition is barred from greatness.

Good and great are seldom in the same man.

He was clearly a man of many qualities, even if they were mostly bad ones.

If you weren't such a great man, you'd be a terrible bore.

He probably was mediocre after all, though in a very honorable sense of that word.

Great men may make great mistakes;

Never expect a perfect work from an imperfect man

What? A great man? I only ever see the ape of his own ideal.

A small man can be just as exhausted as a great man.

No man is great if he thinks he is.

He's not perfect. You are not either

All his life he tried to be a good person. Many times, however, he failed.
For after all, he was only human. He wasn't a dog.

It was a pity that with his great qualities, his unselfishness and honor, his intelligence and sensibility, he should be so unlovable.

A man is great not because he hasn't failed; a man is great because failure hasn't stopped him.
