In vain do we strive to collect them together under the same horizon, or to force them into the same channel; ever do they release themselves from our grasp in order to assume elsewhere the place assigned to them by truth. We should therefore be compelled either to limit ourselves to generalities yielding but little instruction to those who have not sounded all their depths, or else continually to interrupt the course of our inquiry, in order to rove from one people to another with an attention which would be continually distracted and soon wearied. It will be more profitable for us to take a narrower range. England, France, and Spain, will supply us with abundant materials for our undertaking. In these countries we shall study political institutions under the different phases and in the various epochs which I have just exhibited before you. There we shall find that these epochs are more clearly defined, and that the chief facts which characterize them appear under more complete and simple forms. In France and Spain, moreover, the general attempts after a representative government, made in the thirteenth, fourteenth, and fifteenth centuries, assumed a more definite shape. We are therefore dissuaded by a variety of considerations from carrying our steps beyond these limits. Our researches will thereby gain both in interest and in solidity. Interest Of The Subject. This interest, gentlemen, I must say at the outset, is not that merely which attaches itself to human affairs, which are ever attractive to man, however trivial may be the attention which he bestows upon them. The study of the ancient political institutions of Europe demands serious and assiduous effort. I am here to share this with you, not to undertake it for you. I shall be frequently obliged to enter into details, which may appear dry at first, but which are important because of the results to which they lead. I shall not content myself with merely presenting before you these results as a general expression of facts; I shall feel called upon to put you in possession of the facts themselves. The truths which they contain must be seen by yourselves to proceed naturally from them, and must not be allowed a final lodgment in your minds except as they are fortified by such evidence as can establish them. {19} Difficulty Of Attaining Truth.
