This whole subject has been so well handled and so amply illustrated by Professor Max Müller in the Second Series of his Lectures on “the Science of Language,” and in Archbishop Trench’s instructive and delightful volumes on “Words,” that I can but refer to these works and make here a few excerpts from them as examples of the general principle of thought to which I have adverted. Locke, as Professor Müller shows, long ago asserted that in all languages “names which stand for things which fall not under our senses have had their first rise from sensible ideas.” Our word “spirit” comes from the Latin _spiritus_, the breath, and _spiro_, to breathe; so _animus_, the soul, a seat of the affections, and _anima_, the living principle, are connected with the Greek ἄνεμος, wind. Indeed, _anima_ is sometimes used in Latin for a breeze, as readers of Horace will remember, and all are connected with the Greek verb ἄω, to blow. πνεῦμα, the Greek word used in Scripture to express spirit and a spiritual being, originally means wind and breath, from the verb πνέω, to blow and to breathe. Again, ψυχή, life and soul, is connected with ψύχω, which in Homer means to breathe, to blow. So that in all these cases we see that men, when they first became aware of an invisible and spiritual principle within themselves, named it by an act of imagination from the most impalpable entity their senses perceived,—the wind, or the breath. Again, take our word “ideal.” It comes from the Greek ἰδέα, from ἰδεῖν, to see, originally a word of sight, expressing the look or appearance of a thing, which Plato in time employed to express the most spiritual entities, the supersensible pattern of all created things. Again, our words “imagination” and “imaginative,” how have they been formed? The Latin word _imaginatio_ occurs but rarely; more frequently the verb _imaginor_, to picture to one’s self; more frequent still is _imago_, as if _imitago_, from _imitor_, to imitate. This last is connected with the Greek verb μιμέομαι, meaning also to imitate; and the original of these, and all the cognate words, both Latin and Greek, is the Sanscrit root _mâ_, to measure. So from this very palpable process of measuring the land, there have been spun all the subtle and delicate words that express the working of imagination. So the mental processes expressed by “apprehend,” “comprehend,” and “conceive,” are all derived from bodily processes, and mean respectively to grasp at a thing with the hand, to grasp a thing together, to take and hold together. Again, the word “perceive,” from the Latin _percipere_, was in the language of husbandry used for the farmer gathering in the fruits of his fields and storing them in his garner. Was then the mind conceived of as a husbandman who gathers in the notices of sense from the outer world, and stores them in an invisible garner? To “inculcate:” here is another mental word borrowed from husbandry. It means to tread or stamp firmly in with the heel, and
