Macromolecular Change and the Synapse
An organism capable of learning must be able to change some internal state whenever it lays down a memory. To learn one habit or to lay down one memory the organism must change at least one state. To learn another habit or to lay down another memory the organism must be able to change at least one different state in addition to the preceding one. For it is difficult to see how an identical change could form the substrate of two different memories. Given this necessity of a different state for each memory, we must suppose that there must be at least as many different changes of state inside the organism as there are memories.
