It was unfortunately essential to the foregoing argument that the worst motives should be assumed on the part of college benefactors. Justice requires ample correction of this point. A conspiracy to influence the social doctrines of our colleges, as we have seen, is neither so inexpensive, so direct, nor so likely to succeed as to commend itself to business men looking for immediate results. No doubt there have been men of wealth who by large and well advertised benefactions to colleges and universities have sought not to influence college teaching but to rehabilitate themselves and their business methods in popular esteem. Conspicuous giving with this penitential purpose in view is not likely to prove very effective, however. The sharp insight as to motives and the half humourous cynicism peculiar to American character are sufficient safeguards against the purchase of undeserved sympathy by rich offenders. In spite of the enormous sums given in the United States not only to the higher educational institutions but also for many other educational and philanthropic purposes, it seems extremely doubtful that public opinion has been affected thereby favourably to plutocratic interests. Few of the great mass are directly touched and consciously benefited by such gifts, but all are able to see (and if not they are helped by radicals to see), the superfluity out of which the donations were made. Benefactors, prospective and actual, must face the certainty of much criticism and misinterpretation. So far as this criticism is unjust it is to be regretted; so far as it is just it contributes materially to social welfare. Investments in business are judged as to their wisdom by the ready tests of profits and permanence; investments in social work are not subject to tests so accurate and so easily applied. To some extent their place is taken by the advice and criticism of workers in the field. Still there is large possibility that gifts for social work may be applied in useless or even in harmful ways. A wise conception of the function of the philanthropist must therefore include a realisation of the value of criticism by specialists, and also a determination either to ignore misinterpretation and unjust criticism, or to await its reversal by a better informed, if somewhat belated public opinion.
