In my previous post, I introduced pancomputationalism–the idea that every physical system performs computations. There are three main versions of pancomputationalism. Unlimited pancomputationalism says that every physical system performs just about any computation you like. For example, a piece of the Berlin wall sitting outside a museum, like the one in …
Most of the philosophers who discuss computation are interested in computation because they are interested in the computational theory of cognition. Cognitive systems are typically assumed to represent things, and computation is supposed to help explain how they represent. So many philosophers conclude that computation is the manipulation of representations. …
John Schwenkler kindly asked me to blog about my new book, Physical Computation: A Mechanistic Account. I am grateful for the invitation. The original motivation for the research that led to the book was to make progress on the vexed question of whether cognition involves computation. That seems to require …
My last post focused on the relationship between minimal phenomenal selfhood in dreams, spatiotemporal self-location, and bodily experience. But there is another and in some ways more traditional way of thinking about the relationship between dreaming and the self. This is to focus on the epistemic relation between the self, …
As we move from wakefulness into sleep onset and through the different stages of sleep, there are concerted changes in brain activity, the way we process external stimuli from the environment, and in the contents and structure of conscious experience. At the same time, the exact relationship between these changes …
We all dream every night, and most of us feel reasonably certain that we know what it is like to dream. But how well do we really know the phenomenology of dreaming? Can we really be certain that in describing our dreams, we are not merely projecting implicit, pretheoretical assumptions …
We spend roughly one third of our lives asleep, and research tells us that a considerable portion of this time is spent dreaming. Yet, most of us rarely remember our dreams, and even when we do, we would be hard-pressed to describe more than a single dream per night. This …
