“The mind can conceive,” he argues, “and consequently can know,” only the _limited, and the conditionally limited_. The unconditionally unlimited, or the _Infinite_, the unconditionally limited, or the _Absolute_, cannot positively be construed to the mind; they can be conceived, only by a thinking away from, or abstraction of, those very conditions under which thought itself is realized; consequently, the notion of the Unconditioned is only negative,—negative of the conceivable itself. For example, on the one hand we can positively conceive, neither an absolute whole, that is, a whole so great, that we cannot also conceive it as a relative part of a still greater whole; nor an absolute part, that is, a part so small, that we cannot also conceive it as a relative whole, divisible into smaller parts. On the other hand, we cannot positively represent, or realize, or construe to the mind (as here understanding and imagination coincide), an infinite whole, for this could only be done by the infinite synthesis in thought of finite wholes, which would itself require an infinite time for its accomplishment; nor, for the same reason, can we follow out in thought an infinite divisibility of parts. The result is the same, whether we apply the process to limitation in _space_, in _time_, or in _degree_. The unconditional negation, and the unconditional affirmation of limitation; in other words, the _infinite_ and _absolute, properly so called_, are thus equally inconceivable to us. As the conditionally limited (which we may briefly call the _conditioned_) is thus the only possible object of knowledge and of positive thought—thought necessarily supposes conditions. To _think_ is to _condition_; and conditional limitation is the fundamental law of the possibility of thought. For, as the greyhound cannot outstrip his shadow, nor (by a more appropriate simile) the eagle outsoar the atmosphere in which he floats, and by which alone he may be supported; so the mind cannot transcend that sphere of limitation, within and through which exclusively the possibility of thought is realized. Thought is only of the conditioned; because, as we have said, to think is simply to condition. The _absolute_ is conceived merely by a negation of conceivability; and all that we know, is only known as ——‘won from the void and formless _infinite_.’
