the assertion reduces itself to this, that it is only certain
collections of attributes which can be conceived to exist
independently; whereas single attributes depend for their existence
upon others. The colour, smoothness or solidity of a table cannot be
conceived apart from the extension, whereas the whole cluster of
attributes which constitutes the table can be conceived to exist
altogether independently of other 'such clusters. We can imagine a
table to exist, if the whole material universe were annihilated, and
but one mind left to perceive it. Apart from mind, however, we cannot
imagine it: since what we call the attributes of a material substance
are no more than the various modes in which we find our minds
affected.

85. The above division of things belongs rather to the domain of
metaphysics than of logic: but it is the indispensable basis of the
division of terms, to which we now proceed.

terms.
