Thomas Carlyle Quote

How were friendship possible? In mutual devotedness to the good and true; otherwise impossible, except as armed neutrality or hollow commercial league. A man, be the heavens ever praised, is sufficient for himself; yet were ten men, united in love, capable of being and of doing what ten thousand singly would fail in. Infinite is the help man can yield to man.
