This much at least is certain, that the one active, inhabited region of the mystery of justice is to be found within ourselves. Other regions lack consistency; they are probably imaginary, and must inevitably be deserted and sterile. They may have furnished mankind with illusions that served some purpose, but not always without doing harm; and though we may scarcely be entitled to demand that all illusions should be destroyed, they should at least not be too manifestly opposed to our conception of the universe. To-day we seek in all things the illusion of truth. It is not the last, perhaps, or the best, or the only one possible; but it is the one which we at present regard as the most honourable and the most necessary. Let us limit ourselves therefore to recognising the admirable love of justice and truth that exists in the heart of man. Proceeding thus, yielding admiration only where it is incontestably due, we shall gradually acquire some knowledge of this passion, which is the distinguishing note of man; and one thing, most important of all, we shall most undoubtedly learn--the means whereby we can purify it, and still further increase it. As we observe its incessant activity in the depths of our heart, the only temple where it can truly be active: as we watch it blending with all that we think, and feel, and do, we shall quickly discover which are the things that throw light upon it, and which those that plunge it in darkness; which are the things that guide it, and which those that lead it astray; we shall learn what nourishes it and what atrophies, what defends and what attacks.
