which is divisible in two dimensions is a plane, that which is divisible in one a line, that which is in no way divisible in quantity is a point or a unit,-that which has not position a unit, that which has position a point. Again, some things are one in number, others in species, others in genus, others by analogy; in number those whose matter is one, in species those whose definition is one, in genus those to which the same figure of predication applies, by analogy those which are related as a third thing is to a fourth. The latter kinds of unity are always found when the former are; e.g. things that are one in number are also one in species, while things that are one in species are not all one in number; but things that are one in species are all one in genus, while things that are so in genus are not all one in species but are all one by analogy; while things that are one by analogy are not all one in genus. Evidently ‘many’ will have meanings opposite to those of ‘one’; some things are many because they are not continuous, others because their matter- either the proximate matter or the ultimate-is divisible in kind, others because the definitions which state their essence are more than one. < div id=“section48” class=“section” title=“7”> 7 Things are said to ‘be’ (1) in an accidental sense, (2) by their own nature. (1) In an accidental sense, e.g. we say ‘the righteous doer is musical’, and ‘the man is musical’, and ‘the musician is a man’, just as we say ‘the musician builds’, because the builder happens to be musical or the musician to be a builder; for here ‘one thing is another’ means ‘one is an accident of another’. So in the cases we have mentioned; for when we say ‘the man is musical’ and ‘the musician is a man’, or ‘he who is pale is musical’ or ‘the musician is pale’, the last two mean that both attributes are accidents of the same thing; the first that the attribute is an accident of that which is, while ‘the musical is a man’ means that ‘musical’ is an accident of a man. (In this sense, too, the not-pale is said to be, because that of which it is an accident is.) Thus when one thing is said in an accidental sense to be another, this is either because both belong to the same thing, and this is, or because that to which the attribute belongs is, or because the subject which has as an attribute that of which it is itself predicated, itself is. (2) The kinds of essential being are precisely those that are indicated by the figures of predication; for the senses of ‘being’ are just as many as these 1585
