It is by their material appearances that, at the outset, the external world and man himself manifest themselves to the human mind. It is only by reflection and by a process of observation within itself that it penetrates beyond mere appearances, and discovers what appearances alone would never enable it to see. To minds at once active and superficial, inquisitive, impatient to acquire science, although not very nice as to the kind, Materialism is a commodious and apparently clear solution of certain difficult and obscure questions which fasten irresistibly upon the human understanding. {337} Besides all this, these questions, and the different solutions of which they are susceptible, have their epochs of ardor or languor, of favor or discredit. In our days, the fruitful activity and the brilliant progress of the sciences of the material world, come in aid of the doctrine of Materialism. This progress is, however, far from being as exclusive of other progress as is often said. Although less popular than a few years ago, Spiritualism has not ceased to be an active and influential doctrine in the elevated region of philosophy, and the Christian awakening persists and develops itself energetically in the face of the adversaries of Christianity. The times in which we live are entitled to more justice than men accord to them; intellectual labors are now very extensive and very varied; the most different tendencies coexist, and pursue their independent career. Even in this, Materialism is again the doctrine of appearances; it is neither so strong nor so near its triumph as it has the air of being. {338} Nothing proves this better than the hesitation and persistent embarrassment of the most distinguished among its adherents. The circumstance noticed by M. de Remusat twenty-five years ago, is recurring at the present day as plainly as ever. Sometimes we find disavowals of the consequences of the principle of Materialism, and attempts of all kinds to escape from those consequences; sometimes we find efforts made to disguise the principle itself under purer colors. A general and enduring instinct in man persists in protesting against the appearances upon which Materialism is founded. Man does not believe either himself or the universe to be exclusively matter. The distinction between matter and mind is a natural and spontaneous, a primitive and permanent, belief of the human race. And is this, then, merely an instinct and an aspiration, a proud pretension of human nature? Is it not, on the contrary, the innate sentiment, the intimate knowledge of that essential fact in humanity of which observation recognizes and evidences the existence? {339}
