because it brings with it no principle of cognition.

It must therefore be a concept of Judgement or derived from one; and a subjective purposiveness of the representation in reference to the Judgement must lie at its basis. That anything is a magnitude (quantum) may be cognised from the thing itself, without any comparison of it with other things; viz. if there is a multiplicity of the homogeneous constituting one thing. But to cognise how great it is always requires some other magnitude as a measure. But because the judging of magnitude depends not merely on multiplicity (number), but also on the magnitude of the unit (the measure), and since, to judge of the magnitude of this latter again requires another as measure with which it may be compared, we see that the determination of the
