Scientists Make Premature Declaration on Consciousness

Several scientists have made a declaration on consciousness.  (You can read coverage from a Scientific American blog here.)

Unfortunately, I think the declaration is more likely to promote confusion rather than clarity. What does it mean to "experience affective states?" What characterizes intentional behavior as such? These are problematic questions and I don't see this declaration helping matters. They seem to be ignoring the difficulties, not overcoming them.

One basic difficulty is that the word "consciousness" has multiple recognized definitions. For most people, I think if you told them octopuses had consciousness, they'd think that octopuses had self-awareness, higher order thoughts about their lives and experiences, and such. But that is not what the science shows. (I'm not saying octopuses don't have these things, but only that the science doesn't show it.) I suspect that the scientists making this declaration take "consciousness" to mean "phenomenal experience." But even then, the topic is incredibly problematic and the science does not really show us anything about it.

For a long time, neuroscientists have made a distinction between emotions and feelings, and have studied emotions in animals other than human beings. (E.g., see Joseph LeDoux's excellent book, The Emotional Brain.)  It's no news that all sorts of animals have emotions. The question of feelings and consciousness is more difficult, and I think these scientists are only giving the illusion of progress.

An Argument For Compatibilism

Compatibilism is the idea that there is no conflict between determinism and free will.  Incompatibilism is the idea that free will cannot exist in a deterministic universe.  There's been a lot of discussion over which view is correct.  What's remarkable about the debate isn't so much the stubbornness or passion which has been exhibited by this or that party, but the fact that the very terms of the debate are controversial.  There is a great deal of confusion about what the key issues in the debate are and how we should be talking about them.  As a result, there is a meta-debate within the debate itself.  You cannot engage in the debate without also engaging in a debate about the debate--about what issues are at stake and about how the issues should be framed.  So here's what I want to do:  I want to explain why I think incompatibilists are doing a very bad job of framing the debate, and also why compatibilism is the most reasonable option on the t...

Sam Harris and the Moral Realism/Moral Relativism Myth

There is a popular misconception that, if you are not a moral realist, you are a moral relativist. Yet, most non-theistic professional philosophers may be neither. As I'll explain, I prefer a variety of anti-realism called moral noncognitivism. First, I want to discuss the moral realism/moral relativism myth. Moral realists believe in objective truths about right and wrong, whereas moral relativists believe that moral truths are subjective, or limited by the beliefs and values of particular communities and cultures. Moral relativists are people who say, for example, that genital mutilation isn't absolutely or universally wrong--it's just wrong for some people. Moral realists respond, "No, genital mutilation really is [or, perhaps, really isn't] wrong, for all people and all times--all things being equal." This is usually how the issue is framed in popular culture, particularly in debates over atheism and the role of religion in society. It is not uncommo...

Luke Skywalker and Rey: Comparing Character Arcs

My second viewing of The Force Awakens only reinforced my admiration.  I'm very impressed by Rey as a character, and so I want to respond to the prevalent criticism that she does not have a satisfying character arc.  I think she stands up better than many people think.  To prove it, let's compare her arc to Luke's in the original Star Wars, Episode 4: A New Hope.   Luke and Rey each have two inner conflicts dealing with the themes of loyalty and trust, but in Rey's case, the conflicts converge and are developed in a more dramatic and I think satisfying way. At the start of Episode IV: A New Hope , Luke wants to be loyal to his aunt and uncle, but also wants to follow his own dreams.  This is his first inner conflict.  His dreams are somewhat vague at first: He wants to get off Tatooine, join the academy, be heroic, etc.  When Ben Kenobi tells him his father was a Jedi Knight killed by Darth Vader, his motivation becomes more focused: He wants to joi...
