INSTANT
Instant, the indivisible formal factor in time that measures substantial change. The partless instant continues and divides the parts of time; were it divisible into sub-instants, no distinction could be made between past and future. Moreover, because no two instants can be continuous or contiguous, a stretch of time must intervene between them. Yet the instant is in and of time: in time, as its term and measure; of time, since pluralized instants furnish its number. Furthermore, only the instant can measure substantial change. If substantial change occurred in a span of time, either primary matter devoid of act would actually exist for an interval, or an individual would be both dead and alive at one and the same time. At the limiting instant a thing is neither dying nor living—it has ceased to exist. Yet the instant of corruption is the starting-point for a new existent, since primary matter is never unactualized (see matter and form). In other words, there is no last instant of life, and there is no next instant following the instant of death, for between any two instants another instant is discernible. Thus as the limit of time, the instant measures substantial change, for a durationless change demands the durationless point of time.
