The others, if they desire some significant indication of what society actually is beyond the teachings of books, require ten or fifteen years of close observation and study to re-think the phrases with which these have filled their memory, to interpret them anew, to make clear their meaning, to get at and verify their sense, to substitute for the more or less empty and indefinite term the fullness and precision of a personal impression.

We have seen how ideas of Society, State, Government, Sovereignty, Rights, Liberty, the most important of all ideas, were, at the close of the eighteenth century, curtailed and falsified; how, in most minds, simple verbal reasoning combined them together in dogmas and axioms; what an offspring these metaphysical simulacra gave birth to, how many lifeless and grotesque abortions, how many monstrous and destructive chimeras.
There is no place for any of these fanciful dreams in the mind of Bonaparte; they cannot arise in it, nor find access to it; his aversion to the unsubstantial phantoms of political abstraction extends beyond disdain, even to disgust.[1152] That which was then called ideology, is his particular bugbear; he loathes it not alone through calculation, but still more through an instinctive demand for what is real, as a practical man and statesman, always keeping in mind, like the great Catherine, "that he is operating, not on paper, but on the human hide, which is ticklish."

If books are useful to him it is to suggest questions, which he never answers but through his own experience.

He has read only a little, and hastily;[1153] his classical education is rudimentary; in the way of Latin, he remained in the lower class.

Next to this, the literature of elegance and refinement, the philosophy of the closet and drawing-room, with which his contemporaries are imbued, glided over his intellect as over a hard rock.

None but mathematical truths and positive notions about geography and history found their way into his mind and deeply impressed it.
Everything else, as with his predecessors of the fifteenth century, comes to him through the original, direct action of his faculties in contact with men and things, through his prompt and sure tact, his indefatigable and minute attention, his indefinitely repeated and rectified divinations during long hours of solitude and silence.
Practice, and not speculation, is the source of his instruction, the same as with a mechanic brought up amongst machinery.
