The acts of the mind, wherein it exerts its power over simple ideas, are chiefly these three:
- Combining several simple ideas into one compound one, and thus all complex ideas are made.
- The second is bring two ideas, whether simple or complex, together, and setting them by one another so as to take a view of them at once, without uniting them into one, by which it gets all its ideas of relations.
- The third is separating them from all other ideas that accompany them in their real existence: this is called abstraction, and thus all its general ideas are made.
------John Locke, An Essay Concerning Human Understanding (1690)
