It is clear enough that nothing needs to _occupy_ space, in order to be a magnitude. A line, which occupies no space, is even a _spatial_ magnitude, nevertheless. That it is spatial, Bergson would say, is just the fact that it is homogeneous. But is homogeneity the only character of a line, and is its spatiality _therefore_ necessarily the same thing as its homogeneity? Evidently a line has a _quale_ perfectly distinct from its homogeneity, and essential to its linear nature; that _quale_ is its direction. If an interval of time, then, or a mental state, seems not to be spatial, this does not compel us to deny that there is any homogeneity about it: if the interval or the state of mind lacks the determination--the character of direction--which is indispensable to a line and to spatiality as such, this lack determines these objects of thought as non-spatial without the slightest detriment to their homogeneity. But all the evidence of homogeneity in space applies equally to homogeneity in time and consciousness. The evidence is their additiveness: all _seem_ to present numerically distinct cases and quantitative differences. No logical ground has been indicated, for discrimination, in the validity of this seeming, as a warrant for the homogeneity of space and not of time and consciousness. Time and consciousness are homogeneous by the same warrant as space and matter. I think it is not irrelevant to Bergson’s theory of the associative transfer of quantity in the stimulus to the sensation, to observe that, in the stimulus, there is kind as well as amount. If the shade or quality of the sensation corresponds to the degree of the cause, is there no further determination of the sensation distinctively correlative with the kind of the cause? Such correlate seems indispensable to Bergson’s, as to any, reactive conception of sensation, but, in Bergson’s theory of intensity, it seems to be preempted for correlation with the aspect of quantity in the stimulus. The case of plural odors and sounds, the case of the line, and an infinity of other cases prove that magnitude is intensive as well as extensive. The contradictory thesis, that of Bergson, reduces, at bottom, to the self-contradiction that consciousness discovers what is no object of consciousness. * * * * *
