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

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.

Brains are not magical; they are causal machines.

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.

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

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

If you give up because you announce the phenomenon cannot be explained, you are missing out.

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.

Suppression of impulses that would put you in danger is obviously an important neurobiological function.

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

Immortality doesn't fit with death, as mortal doesn't fit with eternity.

Death is just a distant rumour to the young.

My Christmas present to myself each year is to see how much air travel can open up the world and take me to places as far from sheltered California and Japan as possible.

And I got a lot of friends in Hollywood.

He who fails to prepare, prepares to fail

I could not have done anymore, I had pushed myself to a limit that I had never touched before and that's definitely going to change you - than going out and doing what you do in practice every day.

I just like doing standup, that's all I'm interested in or good at.

There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.

I think my path would have always gone back to or delivered me to wildlife. I think wildlife is just like a magnet, and it's something that I can't help.

It is with a pious fraud as with a bad action; it begets a calamitous necessity of going on.
