no virtue which has its roots in fear is much to be admired.

Context

“I will not argue the question how far such aberrations can justly be charged against Christianity, but I will admit that I agree with Nietzsche in thinking Dostoevsky’s prostration contemptible. A certain uprightness and pride and even self-assertion of a sort, I should agree, are elements in the best character; no virtue which has its roots in fear is much to be admired. There are two sorts of saints: the saint by nature, and the saint from fear. The saint by nature has a spontaneous love of mankind; he does good because to do so gives him happiness. The saint from fear, on the other hand, like the man who only abstains from theft because of the police, would be wicked if he were not restrained by the thought of hell-fire or of his neighbours’ vengeance.” source
