I did not, however, think that in a work of this description the additional words which would have been required for scientific accuracy were worth the paper and ink and loss of breadth which their introduction would entail. Besides, I know nothing about science, and it is as well that there should be no mistake on this head; I neither know, nor want to know, more detail than is necessary to enable me to give a fairly broad and comprehensive view of my subject. When for the purpose of giving this, a matter importunately insisted on being made out, I endeavoured to make it out as well as I could; otherwise—that is to say, if it did not insist on being looked into, in spite of a good deal of snubbing, I held that, as it was blurred and indistinct in nature, I had better so render it in my work.
Nevertheless, if one has gone for some time through a wood full of burrs, some of them are bound to stick. I am afraid that I have left more such burrs in one part and another of my book, than the kind of reader whom I alone wish to please will perhaps put up with. Fortunately, this kind of reader is the best-natured critic in the world, and is long suffering of a good deal that the more consciously scientific will not tolerate; I wish, however, that I had not used such expressions as “centres of thought and action” quite so often.
As for the kind of inaccuracy already alluded to, my reader will not, I take it, as a general rule, know, or wish to know, much more about science than I do, sometimes perhaps even less; so that he and I shall commonly be wrong in the same places, and our two wrongs will make a sufficiently satisfactory right for practical purposes.
Of course, if I were a specialist writing a treatise or primer on such and such a point of detail, I admit that scientific accuracy would be _de rigueur_; but I have been trying to paint a picture rather than to make a diagram, and I claim the painter’s license “_quidlibet audendi_.” I have done my utmost to give the spirit of my subject, but if the letter interfered with the spirit, I have sacrificed it without remorse.
