Here again one cannot charge education with our lack of men of character, intelligence and capacity to lead; as before, the causes lie far deeper, but the almost fatal absence at this time of the personalities of such force and power that they can captain society in its hours of danger from war or peace, must give us some basis for estimating the efficiency of our educational theory and practice, and again raise doubts as to whether here also we shall be well advised if we rely exclusively upon it as the ultimate saviour of society, while we are bound to ask whether its methods, even of developing intelligence and capacity, are the best that can be devised. Another point worth considering is this. So long as we could lay the flattering unction to our souls that acquired characteristics were heritable, and that therefore if an outcast from Posen, migrating to America, had taken advantage of his new opportunities and so had developed his character-potential, amassed money and acquired a measure of education and culture, he would automatically transmit something of this to his offspring, who would start so much the further forward and would tend normally to still greater advance, and so on _ad infinitum,_ so long we were justified in enforcing the widest measure of education on all and sundry, and in waiting in hope for a future when the cumulative process should have accomplished its perfect work. Now, however, we are told that this hope is vain, that acquired characteristics are not transmitted by heredity, and that the old folk-proverb "it is only three generations between shirtsleeves and shirtsleeves," is perhaps more scientifically exact than the evolutionary dictum of the nineteenth century. Which is what experience and history have been teaching, lo, these many years. The question then seems to divide itself into three parts; (a) are we justified in pinning our faith in ultimate social salvation to free, secular, and compulsory education carried to the furthest possible limits; (b) if not, then what precisely is the function of formal education; and (c) this being determined, is our present method adequate, and if not how should it be modified? It is unwise to speak dogmatically along any of these lines, they are too blurred and uncertain. I can only express an individual opinion. It seems to me that life unvaryingly testifies to the extreme disparity of potential in individuals and in families and in racial strains, though in the two latter the difference is not necessarily absolute and permanent, but variable in point of both time and degree. In individuals the limit of this potentiality is inherent, and it can neither be completely inhibited by adverse education and environment nor measurably extended by favourable education and environment. Characteristics acquired _outside_ inherent limitations are personal and non-heritable, however intimately they may have become a part of the individual himself.
