Thank you for a thoughtful reply, and my appologies for only responding to what appear to be the key points, life has decided to get busy.

You are correct in saying that the animal behaviours discussed are largely evolutionary, the question is what the driver is. Maybe I am being too cynical, but in each example I see a behaviour that is tailored to the benefit of the individual and their genetic line, rather than to the benefit of the group as a whole.

The horses forming a defensive ring have their young on the inside, and are acting to protect them, not the young of others. The person acting to put out the fire at a neighbour’s house seeks to stop it spreading to their house (look at reports of historical fires in cities for many examples) or to encourage others to help them in times of trouble. Kittens playing together rather than attempting to kill their siblings benefit directly from the play, and lack the necessary strength to kill anyway. Other species’ young are not so delicate. Any altruistic behaviour can be framed as selfish when you consider the benefits the individual gains, both in terms of a positive feeling and in terms of social ‘credit’ for want of a better term, although that take may really be too cynical for most.

One of the most obvious ways to see how selfish these behaviours are is to see what happens when they don’t work out for some reason, say lack of resources, or where a larger benefit can be gained by acting differently. Lions kill each others cubs, in many species the strong will monopolise resources to the detriment of weaker members of society, others will steal cached food from members of their own kind. Even herd animals will leave the slowest members behind if it means personal survival.

As I said, I do think humans would benefit from much more cooperation, but I think Kropotkin’s point is weak and mostly relies on the reader thinking the animals mentioned are cute and fluffy, or majestic, rather than thinking about their behavior. I think his point would have been better made by comparison to either bees or ants, which clearly operate communally, with little regard to individual benefit. They’re perhaps not so pleasant a comparrison, and are notably hierarchical with a ‘queen’ as the topmost tier, but, to me, they seem to fit his argument better.
