Studies of decision-making in the monkey, where activity of single neurons in parietal cortex is recorded, you can see a lot about the time-accuracy trade-off in the monkey's decision, and you can see from the neuron's activity at what point in his accumulation of evidence he makes his decision to make a particular movement.

Eventually I realized that for contemporary philosophers conceptual analysis per se was an end in itself. For some, it was somehow supposed to lead to the truth about these phenomena, not just to tidy things up a bit.

It is important to understand that while oxytocin may be the hub of the evolution of the social brain in mammals, it is part of a very complex system. Part of what it does is act in opposition to stress hormones, and in that sense release of oxytocin feels good - as stress hormones and anxiety do not feel good.

Even philosophers who did not mind psychology, claimed the brain was irrelevant because it was the hardware, and we only need to know about the software.

Knowing about the neurobiological and evolutionary basis for social behavior can soften the arrogance and self-righteousness that often attends discussions of morality. It may help us all to think a little more carefully and rationally.

There are many levels of organization in nervous systems. Hence we aim to explain mechanisms at one level in terms of properties and dynamics at a lower level, and to fit that in with the properties at the higher levels.
