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.

Brains are not magical; they are causal machines.

Although many philosophers used to dismiss the relevance of neuroscience on grounds that what mattered was the software, not the hardware, increasingly philosophers have come to recognize that understanding how the brain works is essential to understanding the mind.

I am less attracted to guesses about what cannot be done, than about making progress on a problem.

Being engaged in some way for the good of the community, whatever that community, is a factor in a meaningful life. We long to belong, and belonging and caring anchors our sense of place in the universe.

Humility bids us to take ourselves as we are; we do not have to be cosmically significant to be genuinely significant.

It seems that the brain has a "small world" architecture - or at least the cortex does. Everything can connect to everything else in a few synaptic steps.

When that theory is isolated from known facts, it is likely not to be productive.

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.

If you want to understand the nature of something, to find out the truth, that is one thing. If you want to play semantics, make up wild thought 'experiments', that is another thing. I am not so interested in the latter, though I do appreciate that it can be fun, however unproductive.

If I want to know how we learn and remember and represent the world, I will go to psychology and neuroscience. If I want to know where values come from, I will go to evolutionary biology and neuroscience and psychology, just as Aristotle and Hume would have, were they alive.

In all probability, mental states are processes and activities of the brain. Exactly what activities, and exactly at what level of description, remains to be seen.

I made the assumption, wrong of course, that conceptual analysis was a brief preliminary on the road to finding out about the nature of free will, consciousness, the self, the origin of values, and so forth.

It is surely important that the differences between coma, deep sleep, being under anesthesia, on the one hand, and being alert on the other, all involve changes in the brain.

Theorizing is of course essential to make progress in understanding, but theorizing in the absence of knowing available relevant facts is not very productive.

The neuroscience of consciousness is not going to stop in its tracks because some philosophers guesses that project cannot be productive.

It seems probable that humans have been on the planet, with much the same brain, for about 250,000 years.

I had no idea what philosophy was until I went to college at UBC. I first read Hume and Plato, so naturally I was under the misapprehension that philosophers are trying to figure out what is true, and that contemporary philosophers are mainly trying to figure out what is true about the mind. Of course Hume and Plato were trying to do that, hence my misapprehension.

Many mammals and birds have systems for strong self-control, and it is not difficult to see why such systems were advantageous and were selected for. Biding your time, deferring gratification, staying still, foregoing sex for safety, and so forth, is essential in getting food, in surviving, and in successful reproduction.
