genus as regards some of its objects; in species as regards others。
Hence too; we may conclude that one can perceive 'numerically
different objects' coinstantaneously with a faculty which is
numerically one and the same; but not the same in its relationship
'sc。 according as the objects to which it is directed are not the
same'。
That every sensible object is a magnitude; and that nothing which it
is possible to perceive is indivisible; may be thus shown。 The
distance whence an object could not be seen is indeterminate; but that
whence it is visible is determinate。 We may say the same of the
objects of Smelling and Hearing; and of all sensibles not discerned by
actual contact。 Now; there is; in the interval of distance; some
extreme place; the last from which the object is invisible; and the
first from which it is visible。 This place; beyond which if the object
be one cannot perceive it; while if the object be on the hither side
one must perceive it; is; I presume; itself necessarily indivisible。
Therefore; if any sensible object be indivisible; such object; if
set in the said extreme place whence imperceptibility ends and
perceptibility begins; will have to be both visible and invisible
their objects; whether regarded in general or at the same time; but
this is impossible。
This concludes our survey of the characteristics of the organs of
Sense…perception and their objects; whether regarded in general or
in relation to each organ。 Of the remaining subjects; we must first
consider that of memory and remembering。
