Letter: Sense of self in science, Shakespeare and trout (3)

Published 3 October 2018

From Daniel Hackett, London, UK

Deleniv suggests self-awareness is an extension of the challenge of dealing with the minds of others: prey, competitors or members of your social group. Territoriality should not be underestimated as an example of such a challenge.

If you put two trout in a small tank, they will skirmish. The loser will change to a dark colour and sulk at the bottom. It “knows” it has been beaten and not to “try it on” until the top trout goes away. It may not have a demonstrable “this is me” mode, but surely this is where individualisation starts – with a kind of awareness of one's own situation.
