Because he believes that the best method of achieving that consummation, having regard to the present level of human intelligence, is by moderate courses, one must not think that he is lukewarm in the cause of religion.

With all the force of his clear and able mind, he believes in moderation.

Anything that in the least degree savours of extravagance seems to him impolitic.

He does not believe in sudden bursts of emotional energy; he believes in constant pressure.
In my intercourse with him I have found him eminently sane and judicial, cold towards excessive fervour, but not cold at all towards ardent faith, inclined perhaps to miss the cause of spiritual impatience, constitutionally averse from any understanding sympathy with religious ecstasy, but never self-satisfied, intolerant, or in the remotest fashion cynical.

Always he expresses his views with modesty, and sometimes with healthy good-humour, disposed to take life cheerfully, never moved to mistake a molehill for a mountain, always quietly certain that he is on the right road, whatever critics may care to say about his pace.
It is perhaps unreasonable to expect height and depth where there is excessive breadth.
