too, it is "better n o t to put the question; for whatever the
answer m ight be, other questions would s till remain. This
one thing greatly perplexed m e, that bodies could be infinitely
subdivided. To th is perhaps an answer has been given, by
setting over against it the converse property o f abstract number
[viz. its susceptibility o f infinite m ultiplication].
3. B ut stay: le t us see w hat is that indefinable object^
w hich is suggested to the m ind. This world w ith which our
senses acquaint us is surely the image of some world which the
understanding apprehenda U"ow it is a strange phenomenon
which w e observe in the images which mirrors reflect to us,—
that however great the mirrors be, they do not make the images
larger than the objects placed before them , be th ey ever so
sm all; but in sm all mirrors, such as th e pupil of the .eye,
although a large surface be placed over against them, a very
sm all image is formed, proportioned to th e size o f th e mirror.*
Therefore if the mirrors be reduced in size, the images reflected
in them are also reduced; but it is not possible for the images
to be enlarged by enlarging the mirrors. Surely there is in this
something which m ight reward further in vestigation ; b u t mean

happy, it is not because I seek, but because perchance I have
found something. W hat, then, is that som ething ? Is it that
chain, of reasoning w hich I am wont so to caress as if it were
m y sole treasure, and in which perhaps I' take too much
delight ?

properties of reflection possessed by convex, plane, and coiiMve mirrors, must have
been lamentably limited.
