When fish experience something that would cause other animals physical pain, they behave in ways suggestive of pain, and the change in behaviour may last several hours.

Effective altruism is the form of altruism in which we bring our rational capacities to bear in order to do the most good that we can.

Remember that not everyone is as strong as you are. Be mindful of human weakness, and of the fact that it may be more important, in the long run, to get many people taking steps in the right direction than to have fewer achieving the ideal.

I can tell you that too much money is corrupting American politics. Don't blame the American public. The U.S. Supreme Court has a lot to answer for, because it has made it impossible for Congress to reduce the corrupting influence of money on American political life.

My fear is that that's what's going to happen with robotics and the military. Importantly, this discussion has to involve not just the scientists, but also the political scientists. It's got to be a multidisciplinary discussion. You can't have it be another repeat of what happened with the people working on the atomic bomb.

...the nervous systems of other animals were not artificially constructed - as a robot might be artificially constructed - to mimic the pain behavior of humans. A capacity to feel pain obviously enhances a species' prospects of survival...it is surely unreasonable to suppose that nervous systems that are virtually identical physiologically, have a common origin and a common evolutionary function, and result in similar forms of behavior in similar circumstances should actually operate in an entirely different manner on the level of subjective feelings.

What is faith? If you believe something because you have evidence for it, or rational argument, that is not faith. So faith seems to be believing something despite the absence of evidence or rational argument for it.
