My dear Watson," said [Sherlock Holmes], "I cannot agree with those who rank modesty among the virtues. To the logician all things should be seen exactly as they are, and to underestimate one's self is as much a departure from truth as to exaggerate one's own powers.
I must apologize for calling so late," said he, "and I must further beg you to be so unconventional as to allow me to leave your house presently by scrambling over your back garden wall.
Yet birth, and lust, and illness, and death are changeless things, and when one of these harsh facts springs out upon a man at some sudden turn of the path of life, it dashes off for the moment his mask of civilization and gives a glimpse of the stranger and stronger face below.
The ideal reasoner, he remarked, would, when he had once been shown a single fact in all its bearings, deduce from it not only all the chain of events which led up to it but also all the results which would follow from it.
I could not rest, Watson, I could not sit quiet in my chair, if I thought that such a man as Professor Moriarty were walking the streets of London unchallenged.

You have attempted to tinge it with romanticism, which produces much the same effect as if you worked a love-story ... Some facts should be suppressed, or, at least, a just sense of proportion should be observed in treating them. The only point in the case which deserved mention was the curious analytical reasoning from effects to causes, by which I succeeded in unravelling it.'' —Sherlock Holmes on John Watson's "pamphlet", "A Study in Scarlet".

Nature is the true revelation of the Deity to man. The nearest green field is the inspired page from which you may read all that it is needful for you to know.
