its contrary; thus motion upwards is the contrary of motion
downwards and vice versa.

In the case of that sort of motion which yet remains, of those
that have been enumerated, it is not easy to state what is its
contrary. It appears to have no contrary, unless one should
define the contrary here also either as 'rest in its quality' or
as 'change in the direction of the contrary quality', just as we
defined the contrary of change of place either as rest in a place
or as change in the reverse direction. For a thing is altered
when change of quality takes place; therefore either rest in its
quality or change in the direction of the contrary may be called
the contrary of this qualitative form of motion. In this way
becoming white is the contrary of becoming black; there is
alteration in the contrary direction, since a change of a
qualitative nature takes place.

Part 15

it is used with reference to habit or disposition or any other
quality, for we are said to 'have' a piece of knowledge or a

regard to apparel, a man being said to 'have' a coat or tunic; or
in respect of something which we have on a part of ourselves, as
a ring on the hand: or in respect of something which is a part of
us, as hand or foot. The term refers also to content, as in the
case of a vessel and wheat, or of a jar and wine; a jar is said
