“In the case of all things which have several parts and in which the totality is not, as it were, a mere heap, but the whole is something besides the parts, there is a cause; for even in bodies contact is the cause of unity in some cases, and in others viscosity or some other such quality.”
I got this from Mark Manson. The original quote we think we know goes like this; the sum of the parts is greater than the whole. Mark points out that almost nothing Aristotle says is all that understandable so I thought I’d give an example above.
Usually I have something pithy today, but I thought I’d throw in an example of something we think we know and really don’t, along with how little we pay attention to history.
