When Clifford speaks of things in themselves he does not mean Kant’s thing in itself, he means neither the object independent of the thinking subject nor the thing independent of space and time. He means the thing as it would be if viewed from the thing itself. A man appears to other thinking beings as an active body, as an organism that is in motion; but to himself he appears as a feeling being. The subjectivity of things as they appear to the things themselves consists in our own case of states of awareness, and this subjectivity is called by Clifford the thing in itself. A certain brain motion is in its subjective aspect a feeling. This feeling is according to Clifford the thing in itself of the visible, observable, and measurable motion. The thing in itself of so-called inanimate beings is not feeling, but elements of feeling. In other words, the world-substance is everywhere in itself potentiality of feeling and Clifford therefore calls it “mind-stuff.” Schopenhauer arrives at his conception of the thing in itself practically in the same way. There is the world as it appears to us, the objective world of motion in space and time. What the kernel of this world may be, we can know from self-observation. The kernel of ourselves, Schopenhauer says, is Will; and the will is also the kernel of things; the will is the thing in itself. We understand by will the passage into action, i. e. an incipient motion of the organism if accompanied with the psychical element of consciousness, and this consciousness is a state of awareness of the will including its direction and aim. Will, as the term is generally used, is always conscious. Schopenhauer however speaks of the will as being blind, i. e. without knowledge, without awareness of itself and its aim. This indicates that he uses the word not in its original but in a figurative meaning. The fall of a stone may be characterised as a blind motion without awareness and without the stone’s having a consciousness as to its direction or aim; and in a similar (although not in the same) way Clifford speaks of the elements of feeling as being not rational. We agree with Schopenhauer that that factor in a stone which makes it fall when placed in a certain position is as much a natural process as the act of a man, only of a lower grade and a simpler kind. Schopenhauer calls that which both have in common “will.” Yet in common language we call the objective aspect of that which both processes have in common, “motion.” What then is the subjective aspect of a falling stone? It is not a state of awareness, it is no feeling, but it is the potentiality of a state of awareness, it is potential feeling. There _is_ a subjective aspect, but this subjective aspect is so far as we can judge of no account to the stone.
