Every object possesses each of these attributes in a definite degree. Let a measure be given for any particular attribute which is capable of being applied to the object; then we may discover the exact extent of that attribute, which it neither exceeds nor falls short of. I measure the height of this tree; it is defined, and it is not a single line higher or lower than it is. I consider the green of its leaves; it is a definite green, not the smallest shade darker or lighter, fresher or more faded than it is; although I may have neither measure nor expression for these qualities. I turn my eye to this plant; it is at a definite stage of growth between its budding and its maturity, not in the smallest degree nearer or more remote from either than it is. Everything that exists is determined throughout; it is what it is, and nothing else.
Not that I am unable to conceive of an object as floating unattached between opposite determinations. I do certainly conceive of indefinite objects; for more than half of my thoughts consist of such conceptions. I think of a tree in general. Has this tree fruit or not, leaves or not; and if so, what is their number?—to what order of trees does it belong?—how large is it?—and so on. All these questions remain unanswered, and my thought is undetermined in these respects; for I did not propose to myself the thought of any particular tree, but of a tree generally. But I deny actual existence to such a tree in thus leaving it undefined. Everything that actually exists has its determinate number of all the possible attributes of actual existence, and each of these in a determinate measure, as surely as it actually exists, although I may admit my inability thoroughly to exhaust all the
