My favorite thought these days concerns an analogy between the human brain and an ant colony.

Hypothetically speaking it is suggested (in Gödel, Escher, Bach) that the whole colony could have a consciousness (and that you could even have conversations with it by “reading” certain ant trails and by manipulating them) while each ant is completely unaware of it (just like a single neuron has no idea of a “thought”). Similarly, the “thought” or even the whole consciousness doesn’t really care about individual neurons or is even aware of them.

There are still certain things I’d disagree with in this analogy, but it gives you lots of things to ponder.

Aunt Hillary is the name of such a colony whose best friend is an ant-eater.
