It may be said that, seeing the result is a joint one, inasmuch as both “res” and “me,” or both luck and cunning, enter so largely into development, neither factor can claim pre-eminence to the exclusion of the other. But life is short and business long, and if we are to get the one into the other we must suppress details, and leave our words pregnant, as painters leave their touches when painting from nature. If one factor concerns us greatly more than the other, we should emphasize it, and let the other go without saying, by force of association. There is no fear of its being lost sight of; association is one of the few really liberal things in nature; by liberal, I mean precipitate and inaccurate; the power of words, as of pictures, and indeed the power to carry on life at all, vests in the fact that association does not stick to the letter of its bond, but will take the half for the whole without even looking closely at the coin given to make sure that it is not counterfeit. Through the haste and high pressure of business, errors arise continually, and these errors give us the shocks of which our consciousness is compounded. Our whole conscious life, therefore, grows out of memory and out of the power of association, in virtue of which not only does the right half pass for the whole, but the wrong half not infrequently passes current for it also, without being challenged and found out till, as it were, the accounts come to be balanced, and it is found that they will not do so. Variations are an organism’s way of getting over an unexpected discrepancy between its resources as shown by the fly-leaves of its own cheques and the universe’s passbook; the universe is generally right, or would be upheld as right if the matter were to come before the not too incorruptible courts of nature, and in nine cases out of ten the organism has made the error in its own favour, so that it must now pay or die. It can only pay by altering its mode of life, and how long is it likely to be before a new departure in its mode of life comes out in its own person and in those of its family? Granted it will at first come out in their appearance only, but there can be no change in appearance without some slight corresponding organic modification. In practice there is usually compromise in these matters. The universe, if it does not give an organism short shrift and eat it at once, will commonly abate something of its claim; it gets tricked out of an additional moiety by the organism; the organism really does pay something by way of changed habits; this results in variation, in virtue of which the accounts are cooked, cobbled, and passed by a series of those miracles of inconsistency which was call compromises, and after this they cannot be reopened—not till next time.
