Tyndall, a year ago, vindicated the deductive method even for the physical sciences. This method is the prerogative of genius. But the inductive method, though slower and more commonplace, is far more sure and convincing. The only real antagonism of method is between the scientific and the traditional or dogmatic. Here I take sides decidedly. I have no confidence in any results which are not won by scientific method and I leave aside all traditional and dogmatic systems as scarcely worth noticing. I insist upon strictness of definition, correctness of analysis, precision in observing phenomena, deliberation in comparison, correctness of inference, and exhaustiveness in generalization. These are what constitute the scientific method as applied to diverse subjects. I vindicate for this department of study the character of a true science — not of a closed and finished science but of a science true by virtue of the methods by which the truth is discovered. We shall find the data of our study to some extent in history and statistics, for I think that it is here that we must look for the facts upon which a true science of politics and political economy is to be built; but our history and our statistics are, as yet, by no means in the form of perfection which is required by the economist if he is to build his science upon them. We shall not therefore shun the a priori process where we are thrown upon it as our only resource, and in discussing the details of practical politics, many of which are unprecedented, we shall have recourse to considerations of expediency as the true rule which governs such matters.
My course for the present year, then, involves for the seniors the study of political economy, with especial reference in the lectures to paper money and tariff. In our English text-book these things are curtly dismissed
