The next step we must take is to see in how many senses one thing is said to be 'in' another.
(1) As the finger is 'in' the hand and generally the part 'in' the whole.
(2) As the whole is 'in' the parts: for there is no whole over and above the parts.
(3) As man is 'in' animal and generally species 'in' genus.
(4) As the genus is 'in' the species and generally the part of the specific form 'in' the definition of the specific form.
(5) As health is 'in' the hot and the cold and generally the form 'in' the matter.
(6) As the affairs of Greece centre 'in' the king, and generally events centre 'in' their primary motive agent.
(7) As the existence of a thing centres 'in its good and generally 'in' its end, i.e. in 'that for the sake of which' it exists.
(8) In the strictest sense of all, as a thing is 'in' a vessel, and generally 'in' place.
One might raise the question whether a thing can be in itself, or whether nothing can be in itself-everything being either nowhere or in something else.
