Change
Change is the process whereby some or all of the properties of a Thing or a Being are added to or subtracted from.
Change occurs in one of two ways:
Generally, if change causes a Thing to move past its systole or diastole, it becomes some Thing else.
In the case of Beings, change cannot affect its Being-ness (a Being cannot become another Being under any circumstances), because no amount of addition or subtraction of its properties will result in it becoming another Being.
However subtracting to or adding to the properties of a Being's nature can change that Beings nature: a Being can become of a lesser nature through the passive systolis imposed by time or by the negative application of active diastolis (diastolis contrary to its nature), or it can become of a greater nature through the positive use of active diastolis (diastolis in accord with its nature) imposed by will.
