Since these two ways of changing exhaust the kinds of change there are, in every instance of change there are two factors present.
Thomas pores over the analysis Aristotle provides of this instance of change and its product.
The first premise is justified by the thought that since there is no generation ex nihilo, in every instance of change something persists while something else is gained or lost.
Second, because Aristotle's hylomorphism was initially developed to handle puzzles of change and generation, its deployment in philosophical psychology is sometimes strained, insofar as Aristotle is not immediately willing to treat every instance of perception and thought as a straightforward instance of change in some continuing subject.
Since what is potential is always in potentiality relative to some range of actualities, and nothing becomes actual of its own accord no pile of bricks, for instance, spontaneously organizes itself into a house or a wall an actually operative agent is required for every instance of change.
For example, when a discrete instance of change in community structure may be expected, such as following a large, intense disturbance event, successive similarity may reveal a substantial change in community structure [11].
For Ad1/ AdC/ AK/ AF orthologues (196 clusters of two or more proteins), 17 instances of changes in gene organization were observed (highlighted in Additional file 3).
But on reflection, that theory doesn't really make sense, because a finding of no jurisdiction under these circumstances would call into question the court's ability to deal with other instances of changed government positions, and would be inconsistent with the action the court took just last week in the prison immunity case.
Other ocular adverse events included single instances of changed refraction resulting in blurred vision, post-injection subconjunctival hemorrhage, forehead rash (above the study eye), ocular pain and redness, and progression of pre-existing cataract and glaucoma that required combined cataract extraction and glaucoma surgery with Ahmed valve implantation in the study eye.
For example, the question of how many parallel changes are required to be recognized as an instance of concerted change is naturally dealt with in our model: the statistical signature of concerted or regular change is that the multiple parallel events are more probable if treated as a single coordinated change than as a collection of independent changes (Box 1).
