I am thinking of a subject of thought. I will tell you some of its attributes. See if you can tell what it is.

It is soft, red, hollow. (Qualities).

It is soiled, faded, old. (Conditions).

It is a sphere. (Class).

It is rubber. (Material).

It bounds and rolls. (Actions).

It is under the table. (Place).

By knowing these attributes, you can make a pretty good picture of the thing. So you see what people mean when they say that a thing is made up of its attributes.
