“Reality, then, in spite of the sceptic’s objections, is truly known to be a connected and self-consistent, or internally coherent, system; can we with equal confidence say anything of the data of which the system is composed? Reflection should convince us that we can at least say as much as this: all the materials or data of reality consist of experience, experience being provisionally taken to mean psychical matter of fact, what is given in immediate feeling. In other words, whatever forms part of presentation, will, or emotion, must in some sense and to some degree possess reality and be a part of the material of which reality, as a systematic whole, is composed; whatever does not include, as part of its nature, this indissoluble relation to immediate feeling, and therefore does not enter into the presentation, will, and emotion, of which psychical life is composed, is not real. The real is experience, and nothing but experience, and experience consists of “psychical matter of fact.” Proof of this proposition can only be given in the same way as of any other ultimate truth, by making a trial of it; if you doubt it you may be challenged to perform the experiment of thinking of anything whatever, no matter what, as real, and then explaining what you mean by its reality. Thus suppose you say “I can think of A as real,” A being anything in the universe; now think, as you always can, of an imaginary or unreal A, and then try to state the difference between the A which is thought of as real and the A which is thought of as merely imaginary. As Kant proved, in the famous case of the real and the imagined hundred dollars, the difference does not lie in any of the qualities or properties of the two A’s; the qualities of the imagined hundred dollars are precisely the same as those of the real sum, only that they are “imaginary.” Like the real dollars, the imagined dollars are thought of as possessing such and such a size, shape, and weight; stamped with such and such an effigy and inscription; containing such and such a proportion of silver to alloy; having such and such a purchasing power in the present condition of the market, and so forth. The only difference is that the real dollars are, or under specified and known conditions may be, the objects of direct perception, while the imaginary ones, because imaginary, cannot be given in direct perception. You cannot see or handle them; you can only imagine yourself doing so. It is in this connection with immediate psychical fact that the reality of the real coins lies. So with any other instance of the same experiment. Show me, we might say, anything which you regard as real,—no matter what it is, a stone wall, an aesthetic effect, a moral virtue,—and I will ask you to think of an unreal and imaginary counterpart of that same thing, and will undertake to prove to you that what makes the difference between the reality and the imagination is always that the real thing is indissolubly connected with the psychical life of a sentient subject, and, as so connected, is psychical matter of fact.” (Taylor, Elements of Metaphysics, 23-24) 

“Two points should be carefully noted if we wish to avoid serious misapprehension. It might be objected, by a disciple of Kant or of Mill, that a thing may be real without ever being given as actual psychical fact in immediate apprehension, so long as its nature is such that it would be psychical fact under known and specified conditions. Many, if not most, of the objects of scientific knowledge, it may be said, are of this kind; they have never entered, possibly never will enter, into the contents of any man’s direct apprehension, yet we rightly call them real, in the sense that they would be apprehended under certain known conditions. Thus I have never seen, and do not expect that any one will ever see, the centre of the earth, or, to take a still stronger case, no one has ever seen his own brain. Yet I call the centre of the earth or my own brain real, in the sense that if I could, without ceasing to live, penetrate to a certain depth below the soil, I should find the centre of the earth; if an opening were made in my skull, and a suitable arrangement of mirrors devised, I should see the reflection of my own brain. A comet may be rushing through unpeopled space entirely unbeheld; yet it does not cease for all that to be real, for if I were there I should see it, and so forth. Hence the Kantian will tell us that reality is constituted by relation to possible experience; the follower of Mill, that it means “a permanent possibility of sensation.” Now, there is, of course, an element of truth in these arguments. It is true that what immediately enters into the course of my own direct perception is but a fragment of the full reality of the universe. It is true, again, that there is much which in its own nature is capable of being perceived by human beings, but will, as far as we can judge, never be perceived, owing to the physical impossibility of placing ourselves under the conditions requisite for perception; there are other things which could only be perceived if some modification could be effected in the structure of our perceptive organs. And it may therefore be quite sufficient for the purposes of some sciences to define these unperceived realities as “possibilities of sensations,” processes which we do not perceive but might perceive under known or knowable conditions. But the definition, it will be seen, is a purely negative one; it takes note of the fact that we do not actually perceive certain things, without telling us anything positive as to their nature. In Metaphysics, where we are concerned to discover the very meaning of reality, we cannot avoid asking whether such a purely negative account of the reality of the greater part of the universe is finally satisfactory. And we can easily see that it is not. For what do we mean when we talk of the “possible”? Not simply “that which is not actual,” for this includes the merely imaginary and the demonstrably impossible. The events of next week, the constitution of Utopia, and the squaring of the circle are all alike in not being actual. Shall we say, then, that the possible differs from the imaginary in being what would, under known conditions, be actual? But again, we may make correct inferences as to what would be actual under conditions suspected, or even known, to be merely imaginary, and no one will maintain that such consequences are realities. If I were at the South Pole I should see the Polar ice, and it is therefore real, you say, though no one actually sees it; but if wishes were horses, beggars would ride, yet you do not say that the riding of beggars is real. Considerations of this kind lead us to modify our first definition of the “possible” which is to be also real. We are driven to say that, in the case of the unperceived real thing, all the conditions of perception except the presence of a percipient with suitable perceptive organs, really exist. Thus the ice at the South Pole really exists, because the only unfulfilled condition for its perception is the presence at the Pole of a being with sense-organs of a certain type. But once more, what do we mean by the distinction between conditions which really exist? We come back once more to our original experiment, and once more, try as we will, we shall find that by the real condition as distinct from the imaginary we can mean nothing but a state of things which is, in the last resort, guaranteed by the evidence of immediate perception. If we take the term “actual” to denote that which is thus indissoluble from immediate apprehension, or is psychical matter of fact, we may sum up our result by saying we have found that the real is also actual, or that there is no reality which is not at the same time an actuality. We shall thus be standing on the same ground as the modern logicians who tell us that there is no possibility outside actual existence, and that statements about the possible, when they have any meaning at all, are always an indirect way of imparting information about actualities. Thus “There really exists ice at the South Pole, though no human eye beholds it,” if it is to mean anything, must mean either that the ice itself, as we should perceive it if we were there, or that certain unknown conditions which, combined with the presence of a human spectator, would yield the perception of the ice, actually exist as part of the contents of an experience which is not our own.” (Taylor, Elements of Metaphysics, 24-26) [Underlining is my own]
