But those scientific men who have given much attention to the study of life in its widest manifestations in plants, in animals and in man himself, have, with great show of unanimity, come to a conclusion which appears to indicate that, although we may improve an individual during his or her lifetime, both in physical capacity or mental and moral power, this improvement is not transmitted in appreciable degree to their offspring, who have therefore to begin again in their lives just where the parents began in theirs. This teaching strongly indicates that parents cannot pass on to their offspring in any but a most limited degree the improvements they themselves have made in their own physical or mental condition, in the same way that they can bequeath to them the purses they have filled. If these conclusions, however, are correct, the action of healthy surroundings will never by itself produce a robust out of a feeble race, nor will the action of the best educational system ever devised develop a race of wise men out of a race of fools. With this non-inheritance of personally-acquired characteristics, the work of individual improvement has to begin again in each generation, for the gained ground is always lost, and racial improvement on these lines must be at best immeasurably slow. Racial change, improvement, or deterioration, is brought about, so the biologists say, by what is termed selection, that is, by the death or non-productiveness of certain individuals of a race, whereby the others alone remain. If this remnant is organically superior, the next generation inheriting only from them will be themselves organically superior, and racial improvement will be brought about. If this teaching be true, it follows that all our efforts for the good of mankind will be of no avail unless selective agencies are maintained, unless we are prepared to see that each generation of children is the product of the best amongst us in our day. It is quite possible therefore that, even under the present conditions of better hygienic education and moral teaching, the race may be deteriorating, and, indeed, from the biological standpoint, there is every reason to suppose that it is. Our present efforts may therefore be, after all, misplaced, so that it behoves us very carefully to study the whole position. We have first critically to examine the arguments which point to the non-inheritance of acquired character, to understand the operation of selection, at present considered to be by far the greatest factor in the production of race change, and then to study man in his modern surroundings, with a view to determining how far these are conducive to his ultimate good, and how they may with greatest advantage be modified, with a view to his improvement and advance.
