i 4 o MYSTICISM AND LOGIC 



(2) the assemblage of all the different particulars which 

 would be called aspects of the sun of eight minutes 

 ago this assemblage is what I define as being the sun oi 

 eight minutes ago. Thus &quot; perspectives &quot; and &quot; things &quot; 

 are merely two different ways of classifying particulars. It 

 is to be observed that there is no a priori necessity for 

 particulars to be susceptible of this double classification. 

 There may be what might be called &quot; wild &quot; particulars, 

 not having the usual relations by which the classification 

 is effected ; perhaps dreams and hallucinations are 

 composed of particulars which are &quot; wild &quot; in this sense. 



The exact definition of what is meant by a perspective 

 is not quite easy. So long as we confine ourselves to 

 visible objects or to objects of touch we might define the 

 perspective of a given particular as &quot; all particulars which 

 have a simple (direct) spatial relation to the given par 

 ticular.&quot; Between two patches of colour which I see 

 now, there is a direct spatial relation which I equally see. 

 But between patches of colour seen by different men 

 there is only an indirect constructed spatial relation by 

 means of the placing of &quot; things &quot; in physical space 

 (which is the same as the space composed of perspec 

 tives). Those particulars which have direct spatial 

 relations to a given particular will belong to the same 

 perspective. But if, for example, the sounds which I 

 hear are to belong to the same perspective with the 

 patches of colour which I see, there must be particulars 

 which have no direct spatial relation and yet belong to 

 the same perspective. We cannot define a perspective 

 as all the data of one percipient at one time, because we 

 wish to allow the possibility of perspectives which are 

 not perceived by any one. There will be need, therefore, 

 in defining a perspective, of some principle derived 

 neither from psychology nor from space. 



Such a principle may be obtained from the considera-
