232 present narrowed down to some one simple emotion or sensation of the body.

The important fact which this 'field' formula commemorates is the indetermination of the margin. Inattentively realized as is the matter which the margin contains, it is nevertheless there, and helps both to guide our behavior and to determine the next movement of our attention. It lies around us like a 'magnetic field,' inside of which our centre of energy turns like a compass-needle, as the present phase of consciousness alters into its successor. Our whole past store of memories floats beyond this margin, ready at a touch to come in; and the entire mass of residual powers, impulses, and knowledges that constitute our empirical self stretches continuously beyond it. So vaguely drawn are the outlines between what is actual and what is only potential at any moment of our conscious life, that it is always hard to say of certain mental elements whether we are conscious of them or not.

The ordinary psychology, admitting fully the difficulty of tracing the marginal outline, has nevertheless taken for granted, first, that all the consciousness the person now has, be the same focal or marginal, inattentive or attentive, is there in the 'field' of the moment, all dim and impossible to assign as the latter's outline may be; and, second, that what is absolutely extra-marginal is absolutely non-existent, and cannot be a fact of consciousness at all.

And having reached this point, I must now ask you to recall what I said in my last lecture about the subconscious life. I said, as you may recollect, that those who first laid stress upon these phenomena could not know the facts as we now know them. My first duty now is to tell you what I meant by such a statement.
