Quote by Aristotle
The void is 'not-being,' and no part of 'what is' is a 'not-being,'; for what 'is' in the strict sense of the term is an absolute plenum. This plenum, however, is not 'one': on the contrary, it is a 'many' infinite in number and invisible owing to the minuteness of their bulk.
Summary
This quote suggests that the concept of 'not-being,' or the void, does not truly exist within the realm of reality. Everything that exists, in the strictest sense, is a part of a complete whole, or a plenum. However, this plenum is not unified but consists of an infinite number of invisible entities, so minute in size that they are imperceptible. The quote emphasizes the idea that even though things may appear empty or void, there is always a multitude of invisible elements that make up the whole.
