Again, it has been often and very truly said that it is not the conscious and self-styled sceptic, as Shelley for example, who is the true unbeliever. Such a man as Shelley will, as indeed his life abundantly proves, have more in common than not with the true unselfconscious believer. Gallio again, whose indifference to religious animosities has won him the cheapest immortality which, so far as I can remember, was ever yet won, was probably if the truth were known, a person of the sincerest piety. It is the unconscious unbeliever who is the true infidel, however greatly he would be surprised to know the truth. Mr. Spurgeon was reported as having recently asked the Almighty to “change our rulers _as soon as possible_.” There lurks a more profound distrust of God’s power in these words than in almost any open denial of His existence. So it rather shocks us to find Mr. Darwin writing (“Plants and Animals under Domestication,” vol. ii., p. 275): “No doubt, in every case there must have been some exciting cause.” And again, six or seven pages later: “No doubt, each slight variation must have its efficient cause.” The repetition within so short a space of this expression of confidence in the impossibility of causeless effects would suggest that Mr. Darwin’s mind at the time of writing was, unconsciously to himself, in a state of more or less uneasiness as to whether effects could not occasionally come about of themselves, and without cause of any sort,—that he may have been standing, in fact, for a short time upon the brink of a denial of the indestructibility of force and matter. In like manner, the most perfect humour and irony is generally quite unconscious. Examples of both are frequently given by men whom the world considers as deficient in humour; it is more probably true that these persons are unconscious of their own delightful power through the very mastery and perfection with which they hold it. There is a play, for instance, of genuine fun in some of the more serious scientific and theological journals which for some time past we have looked for in vain in “—.” The following extract, from a journal which I will not advertise, may serve as an example:
