"One cannot learn from someone whom one distrusts."

Next Quote

If, on a full and final review, my life and practice shall be found unworthy of my principles, let due infamy be heaped on my memory; but let none be led thereby to distrust the principles to which I proved recreant, nor yet the ability of some to adorn them by a suitable life and conversation. To unerring time be all this committed.

— Horace Greeley
