(7) 74 HENRY RUTGERS MARSHALL: time, series of secondary presentations of quite another nature, say, for instance, thoughts of the studies I am making, and a vast complex of less definite imagined objects and relations, one of which perchance may be what we call " a previous perception of my friend". The formula (6) above may symbolise such a secondary presentation (say what I call " a previous perception of my friend "), and it is easy to see that we may have at one moment a still more complex presentation of the following form in which we shall have together, in condition for com- parison, both a primary presentation, and a secondary pre- sentation derived from what was a closely allied primary presentation. fpi- 2 _345l e 3 v /s fThe perception o A||-{f ' }>; y-2-* *; pi-23. pi-z. p i^ my friend befor me.

It is clear that here we have a case in which comparison is possible ; which involves a complex presentation of triple emphasis ; A and B in symbol (7) constituting two of these emphases, and the " sense of likeness " the third. But as all know who have given serious attention to the real meaning of likeness and unlikeness, 1 because we say that two of the partial emphases within the complex presentation of triple emphasis is alike, gives us no ground for holding that we have here an old presentation reproduced. As we have already said above, a bond of identity exists, but this iden- tity is in the complex presentation of the moment of comparison. Sec. 14. In order that we may examine this specific pro- cess of comparison without the disturbance of a too cumber- some symbolisation, let us agree to overlook the fact that secondary presentations inhere in primary presentations, and let us use the letter A to represent a given primary presenta- tion. I look at my watch held in my hand and I have (A) a primary presentation of the watch. When I put my watch in my pocket I no longer have the primary presentation (A), Cf.
