properties are represented--only by the configuration of objects that they
are produced.


2.0232 In a manner of speaking, objects are colourless.


2.0233 If two objects have the same logical form, the only distinction
between them, apart from their external properties, is that they are
different.


2.02331 Either a thing has properties that nothing else has, in which case
we can immediately use a description to distinguish it from the others and
refer to it; or, on the other hand, there are several things that have the
whole set of their properties in common, in which case it is quite
impossible to indicate one of them. For it there is nothing to distinguish
a thing, I cannot distinguish it, since otherwise it would be distinguished
after all.


2.024 The substance is what subsists independently of what is the case.


2.025 It is form and content.


2.0251 Space, time, colour (being coloured) are forms of objects.
