'Our knowledge,' writes Grote, 'may be contemplated in either of two ways, or, to use other words, we may speak in a double manner of the "object" of knowledge. That is, we may either use language thus: we KNOW a thing, a man, etc.; or we may use it thus: we know such and such things ABOUT the thing, the man, etc. Language in general, following its true logical instinct, distinguishes between these two applications of the notion of knowledge, the one being yvwvai, noscere, kennen, connaitre, the other being eidevai, scire, wissen, savoir. In the origin, the former may be considered more what I have called phenomenal--it is the notion of knowledge as ACQUAINTANCE or familiarity with what is known; which notion is perhaps more akin to the phenomenal bodily communication, and is less purely intellectual than the other; it is the kind of knowledge which we have of a thing by the presentation to the senses or the representation of it in picture or type, a Vorstellung. The other, which is what we express in judgments or propositions, what is embodied in Begriffe or concepts without any necessary imaginative representation, is in its origin the more intellectual notion of knowledge. There is no reason, however, why we should not express our knowledge, whatever its kind, in either manner, provided only we do not confusedly express it, in the same proposition or piece of reasoning, in both.' Now obviously if our supposed feeling of Q is (if knowledge at all) only knowledge of the mere acquaintance-type, it is milking a he-goat, as the ancients would have said, to try to extract from it any deliverance ABOUT anything under the sun, even about itself. And it is as unjust, after our failure, to turn upon it and call it a psychical nothing, as it would be, after our fruitless attack upon the billy-goat, to proclaim the non-lactiferous character of the whole goat-tribe. But the entire industry of the Hegelian school in trying to shove simple sensation out of the pale of philosophic recognition is founded on this false issue. It is always the 'speechlessness' of sensation, its inability to make any 'statement,'[Footnote: See, for example, Green's Introduction to Hume's Treatise of Human Nature, p. 36.] that is held to make the very notion of it meaningless, and to justify the student of knowledge in scouting it out of existence. 'Significance,' in the sense of standing as the sign of other mental states, is taken to be the sole function of what mental states we have; and from the perception that our little primitive sensation has as yet no significance in this literal sense, it is an easy step to call it first meaningless, next senseless, then vacuous, and finally to brand it as absurd and inadmissible. But in this universal liquidation, this everlasting slip, slip, slip, of direct acquaintance into knowledge-ABOUT, until at last nothing is left about which the knowledge can be supposed to obtain, does not all
