It thus appeared, that both Macaulay and my father were wrong; the one in assimilating the method of philosophizing in politics to the purely experimental method of chemistry; while the other, though right in adopting a deductive method, had made a wrong selection of one, having taken as the type of deduction, not the appropriate process, that of the deductive branches of natural philosophy, but the inappropriate one of pure geometry, which, not being a science of causation at all, does not require or admit of any summing-up of effects.

A foundation was thus laid in my thoughts for the principal chapters of what I afterwards published on the Logic of the Moral Sciences; and my new position in respect to my old political creed, now became perfectly definite.
If I am asked, what system of political philosophy I substituted for that which, as a philosophy, I had abandoned, I answer, No system: only a conviction that the true system was something much more complex and many-sided than I had previously had any idea of, and that its office was to supply, not a set of model institutions, but principles from which the institutions suitable to any given circumstances might be deduced.

The influences of European, that is to say, Continental, thought, and especially those of the reaction of the nineteenth century against the eighteenth, were now streaming in upon me.

They came from various quarters: from the writings of Coleridge, which I had begun to read with interest even before the change in my opinions; from the Coleridgians with whom I was in personal intercourse; from what I had read of Goethe; from Carlyle's early articles in the _Edinburgh_ and Foreign Reviews, though for a long time I saw nothing in these (as my father saw nothing in them to the last) but insane rhapsody.

From these sources, and from the acquaintance I kept up with the French literature of the time, I derived, among other ideas which the general turning upside down of the opinions of European thinkers had brought uppermost, these in particular: That the human mind has a certain order of possible progress, in which some things must precede others, an order which governments and public instructors can modify to some, but not to an unlimited extent: that all questions of political institutions are relative, not absolute, and that different stages of human progress not only _will_ have, but _ought_ to have, different institutions: that government is always either in the hands, or passing into the hands, of whatever is the strongest power in society, and that what this power is, does not depend on institutions, but institutions on it: that any general theory or philosophy of politics supposes a previous theory of human progress, and that this is the same thing with a philosophy of history.
