1. The function of science is to investigate truth. Science is colorless and impersonal. It investigates the force of gravity, and finds out the laws of that force, and has nothing to do with the weal or woe of men under the operation of the law. 2. The moral deductions as to what one ought to do are to be drawn by the reason and conscience of the individual man who is instructed by science. Let him take note of the force of gravity, and see to it that he does not walk off a precipice or get in the way of a falling body. 3. On account of the number and variety of perils of all kinds by which our lives are environed, and on account of ignorance, carelessness, and folly, we all neglect to obey the moral deductions which we have learned, so that, in fact, the wisest and the best of us act foolishly and suffer. 4. The law of sympathy, by which we share each others' burdens, is to do as we would be done by. It is not a scientific principle, and does not admit of such generalization or interpretation that A can tell B what this law enjoins on B to do. Hence the relations of sympathy and sentiment are essentially limited to two persons only, and they cannot be made a basis for the relations of groups of persons, or for discussion by any third party. Social improvement is not to be won by direct effort. It is secondary, and results from physical or economic improvements. That is the reason why schemes of direct social amelioration always have an arbitrary, sentimental, and artificial character, while true social advance must be a product and a growth. The efforts which are being put forth for every kind of progress in the arts and sciences are, therefore, contributing to true social progress. Let any one learn what hardship was involved, even for a wealthy person, a century ago, in crossing the Atlantic, and then let him compare that hardship even with a steerage passage at the present time, considering time and money cost. This improvement in transportation by which "the poor and weak" can be carried from the crowded centres of population to the new land is worth more to them than all the schemes of all the social reformers. An improvement in surgical instruments or in anaesthetics really does more for those who are not well off than all the declamations of the orators and pious wishes of the reformers. Civil service reform would be a greater gain to the laborers than innumerable factory acts and eight-hour laws. Free trade would be a greater blessing to "the poor man" than all the devices of all the friends of humanity if they could be realized. If the economists could satisfactorily solve the problem of the regulation of paper currency, they would do more for the wages class than could be accomplished by all the artificial doctrines about wages which they seem to feel bound to encourage. If we could get firm and good laws passed for the management of savings-banks, and then refrain from the amendments by which those laws are gradually broken
