nd ‘speed’ are common to both contraries; for each of them has two meanings-’weight’ means both that which has any amount of gravity and that which has an excess of gravity, and ‘speed’ both that which has any amount of movement and that which has an excess of England Drakt movement; for even the slow has a certain speed and the comparatively light a certain weight.)
In all these, then, the measure and starting-point is something one and indivisible, since even in lines we treat as indivisible the line a foot long. For everywhere we seek as the measure something one and indivisible; and this is that Arsenal Drakter which is simple either in quality or in quantity. Now where it is thought impossible to take away or to add, there the measure is exact (hence that of number is most exact; for we posit Paul Pogba Pelipaita the unit as indivisible in every Atletico Madrid Drakter respect); but in all other cases we imitate this sort of measure. For in the case of Aston Villa Pelipaita a furlong or a talent or of anything comparatively large any addition or subtraction might more easily escape our notice than in the case of something smaller; so that the first thing from which, as far as our perception goes, nothing can be subtracted, Gil Pelipaita all men make the measure, whether of liquids or of solids, whether Nike Roshe Run Womens of weight or of size; and they think they know the quantity when they know it by means of this measure. And Chile Drakt Barn indeed Thomas Vermaelen Pelipaita they know movement too by the simple movement and Isco Pelipaita the quickest; for this occupies least time. And so in astronomy a ‘one’ of this sort is the starting-point and measure (for they assume the movement of the heavens to be uniform and the quickest, and judge the others by reference to it), and in Lukasz Skorupski Pelipaita music the quarter-tone (because it is the least interval), and in speech the Andriy Yarmolenko Pelipaita letter. And all these are ones in this sense — not that ‘one’ is something predicable in the same sense of all of these, but in the sense we have mentioned.
But the measure is not always one in number — sometimes there are several; e.g. the quarter-tones (not to the ear, but as determined by the ratios) are two, and the articulate sounds by which we measure are more than one, and the diagonal of the square and its side are measured by two quantities, and all spatial magnitudes reveal similar varieties of unit. Thus, then, the one is the measure of all things, because we come to know the elements in the substance by dividing the things either in respect of quantity or in respect of kind. And the one is indivisible just because the first of each class of things is indivisible. But it is not in the same way that every ‘one’ is indivisible e.g. a foot and a unit; the latter is indivisible in every respect, while the former must be placed among things which are undivided to perception, as has been said already-only to perception, for doubtless every continuous thing is divisible.
The measure is always homogeneous with the thing measured; the measure of spatial magnitudes is a spatial magnitude, and in particular that of length is a length, that of breadth a breadth, that of articulate sound an articulate sound, thlinks:
