We can study philology and craniology in the library and in solitude, assisted by proper documents and sufficient materials, _but not anthropology_; because anthropology is a science still in its cradle, and observation must have furnished its proper and necessary contingent before we can endeavour to apply any general idea or view. But anthropology ought, more especially, to disengage itself from all trammels of former ideas, as well as from all pretended humanitarian tendencies. It would be nonsense to believe that the advance of the truth will not contribute to social progress. The searcher after it can free himself in all tranquillity of mind from this kind of trouble. Haller has said, in reference to this matter, “The cultivation of truth alone is sufficient for the good man.”[359] That which is true,[360] cannot be evil, because it is in the eternal order of nature. Thus, free from fetters, and obeying pure reason, resting on all the sciences which can assist it, anatomy, physiology, psychology, and philology, the science of mankind will advance, like every other science, towards the conquest of that truth which is so much to be desired; and sooner or later, by means of archæology and palæontology, retracing its steps in the past beyond history itself, and beyond the remotest geological epochs of which we have any record, science will eventually discover the grand problem of the origin of mankind, if the elements themselves are not for ever engulphed in the depths of the ocean.
