And that in a sense unity means the same as being is clear from the fact that it follows the categories in as many ways, and is not comprised within any category, eg neither in substance nor in quality, but is related to them just as being is; and from the fact that in 'one man' nothing more is predicated than in 'man', just as being is nothing apart from substance or quality or quantity; and to be one is just to be a particular thing.
