Essentially this idea is to present a sort of stratification in human ideas. I have it very much in mind that various terms in our reasoning lie, as it were, at different levels and in different planes, and that we accomplish a large amount of error and confusion by reasoning terms together that do not lie or nearly lie in the same plane.
Let me endeavour to make myself a little less obscure by a most flagrant instance from physical things. Suppose some one began to talk seriously of a man seeing an atom through a microscope, or better perhaps of cutting one in half with a knife. There are a number of non-analytical people who would be quite prepared to believe that an atom could be visible to the eye or cut in this manner. But any one at all conversant with physical conceptions would almost as soon think of killing the square root of 2 with a rook rifle as of cutting an atom in half with a knife. Our conception of an atom is reached through a process of hypothesis and analysis, and in the world of atoms there are no knives and no men to cut. If you have thought with a strong consistent mental movement, then when you have thought of your atom under the knife blade, your knife blade has itself become a cloud of swinging grouped atoms, and your microscope lens a little universe of oscillatory and vibratory molecules. If you think of the universe, thinking at the level of atoms, there is neither knife to cut, scale to weigh nor eye to see. The universe at that plane to which the mind of the molecular physicist descends has none of the shapes or forms of our common life whatever. This hand with which I write is in the universe of molecular physics a cloud of warring atoms and molecules, combining and recombining, colliding, rotating, flying hither and thither in the universal atmosphere of ether.
You see, I hope, what I mean, when I say that the universe of molecular physics is at a different level from the universe of common experience;—what we call stable and solid is in that world a freely moving system of interlacing centres of force, what we call colour and sound is there no more than this length of vibration or that. We have reached to a conception of that universe of molecular physics by a great enterprise of organised analysis, and our universe of daily experiences stands in relation to that elemental world as if it were a synthesis of those elemental things.
I would suggest to you that this is only a very extreme instance of the general state of affairs, that there may be finer and subtler differences of level between one term and another, and that terms may very well be thought of as lying obliquely and as being twisted through different levels.
It will perhaps give a clearer idea of what I am seeking to convey if I suggest a concrete image for the whole world of a man's thought and knowledge. Imagine a large clear jelly, in which at all angles and in all states of simplicity or contortion his ideas are imbedded. They are all valid and possible ideas as they lie, none in reality incompatible with any. If you imagine the direction of up or down in this clear jelly being as it were the direction in which one moves by analysis or by synthesis, if you go down for example from matter to atoms and centres of force and up to men and states and countries—if you will imagine the ideas lying in that manner—you will get the beginning of my intention. But our Instrument, our process of thinking, like a drawing before the discovery of perspective, appears to have difficulties with the third dimension, appears capable only of dealing with or reasoning about ideas by projecting them upon the same plane. It will be obvious that a great multitude of things may very well exist together in a solid jelly, which would be overlapping and incompatible and mutually destructive, when projected together upon one plane. Through the bias in our Instrument to do this, through reasoning between terms not in the same plane, an enormous amount of confusion, perplexity and mental deadlocking occurs.
The old theological deadlock between predestination and free-will serves admirably as an example of the sort of deadlock I mean. Take life at the level of common sensation and common experience and there is no more indisputable fact than man's freedom of will, unless it is his complete moral responsibility. But make only the least penetrating of analyses and you perceive a world of inevitable consequences, a rigid succession of cause and effect. Insist upon a flat agreement between the two, and there you are! The Instrument fails.
It is upon these three objections, and upon an extreme suspicion of abstract terms which arises materially out of my first and second objections, that I chiefly rest my case for a profound scepticism of the remoter possibilities of the Instrument of Thought. It is a thing no more perfect than the human eye or the human ear, though like those other instruments it may have undefined possibilities of evolution towards increased range, and increased power.
So much for my main contention. But before I conclude I may—since I am here—say a little more in the autobiographical vein, and with a view to your discussion to show how I reconcile this fundamental scepticism with the very positive beliefs about world-wide issues I possess, and the very definite distinction I make between right and wrong.
I reconcile these things by simply pointing out to you that if there is any validity in my image of that three dimensional jelly in which our ideas are suspended, such a reconciliation as you demand in logic, such a projection of the things as in accordance upon one plane, is totally unnecessary and impossible.
This insistence upon the element of uniqueness in being, this subordination of the class to the individual difference, not only destroys the universal claim of philosophy, but the universal claim of ethical imperatives, the universal claim of any religious teaching. If you press me back upon my fundamental position I must confess I put faith and standards and rules of conduct upon exactly the same level as I put my belief of what is right in art, and what I consider right practice in art. I have arrived at a certain sort of self-knowledge and there are, I find, very distinct imperatives for me, but I am quite prepared to admit there is no proving them imperative on any one else. One's political proceedings, one's moral acts are, I hold, just as much self-expression as one's poetry or painting or music. But since life has for its primordial elements assimilation and aggression, I try not only to obey my imperatives, but to put them persuasively and convincingly into other minds, to bring about my good and to resist and overcome my evil as though they were the universal Good and the universal Evil in which unthinking men believe. And it is obviously in no way contradictory to this philosophy, for me, if I find others responding sympathetically to any notes of mine or if I find myself responding sympathetically to notes sounding about me, to give that common resemblance between myself and others a name, to refer these others and myself in common to this thing as if it were externalised and spanned us all.
