PBESENTATION AND EEPBESENTATION. 65 The primary presentation in this typical case may be re- presented by the symbol , (1) in which the numbers symbolise the emphasised partial constituents of the complex primary presentation, and the marks ~ symbolise relations, of any determinate charac- ter, which exist between these partial constituents. The secondary presentation which I experience when in the second moment I close my eyes may then be, in like manner, represented by the symbol he small p being used in place of the large P to indicate the evident difference of emphasis, or vividness as we say, be- tween the primary and secondary presentations ; the numbers and symbols of relation being retained to indicate the evident likeness of general nature existing between the primary and the secondary presentations ; the number 5 however being dropped, to indicate, what is equally evident, that some of the elements which appear in the primary presentation of one moment are lost in the corresponding secondary presen- tation of the following moment. If I keep my eyes closed, this secondary presentation changes, as we have seen, in clearness and definiteness, and part from complications these changes appear to con- iist, largely at all events, in the dropping out of emphasis of me of the partial constituents of the secondary presentation mbolised by the numbers 1, 2, 3 and 4 in the formula (2). I keep my eyes closed for four successive units of time (which I speak of as moments) these images or secondary presentations which I experience may then be symbolised as follows : The five presentations of these five successive moments, as usually considered, may therefore thus be symbolised as follows : (1) pi-2_34 5, ( 2 ) Ji-2-8 *, (3) y~ 2 - 3 , (4) Ji~ 2 , (5) p This is what happens if after the first moment I close my eyes. But if in, let us say, the fourth moment, I had opened my eyes, then I should have had quite a different experience. a _ For then, instead of secondary presentation, p 1 ~ 2 , I should have found myself experiencing a new primary presentation, 5
