Puzzles of Color The mantis shrimp challenges philosophical reflection. This little crustacean is reputed to have the most complex eyes in the animal kingdom. Mounted on stalks, these eyes can move independently and rotate freely; it has between 12 and 16 photoreceptors compared to the human 3. It can see into what is […]
I have been writing songs lately, so I thought I’d share this one with you: think of it as sung in Country and Western style. The Ballad of Dolores Haze He broke my heart But you broke my life He was a creature of art You were a monster equipped with a […]
Partial Skepticism The solipsist is a partial skeptic: he doubts the existence of other beings, sentient or otherwise, but he doesn’t doubt his own existence. He might go on positively to affirm that nothing exists but himself. He favors one object over all others. What is the analogue of this for the material […]
Stereotypes Wittgenstein warned against the “craving for generality”: the mistaken desire to find uniformity where there is only diversity. Thus philosophers are apt to suppose that all words are names, all sentences are assertions, and all states of mind are experiential—despite a heterogeneity that is evident to unbiased inspection. In a word, […]
Ignorance and Solipsism Is it possible to refute solipsism-of-the-moment? Is it possible to show that there must be more to the world than oneself and one’s current state of consciousness? The standard approach has been to assert that certain propositions about the world beyond consciousness are indubitable—say, the proposition that I have […]
How Things Really Look I wish to defend the legitimacy of a metaphysical concept that I have not seen discussed before: the concept of what might be called objective appearance. We are familiar with the concept of subjective appearance—the ways things appear to specific organisms with specific sensory faculties. These vary from case […]
Let me clarify something: the essays I post here are not really intended as conventional blog posts. They are papers I write as part of my ongoing research. I publish them here because it is easier and quicker than going through the usual publication channels, which for various reasons is not feasible for me now. […]
Pathological Belief There is something funny about belief: belief isn’t quite right in the head. The human belief system leaves a lot to be desired. Philosophers have been onto this for a while, noting the peculiarities of belief. Early on it was noticed that belief reports are referentially opaque: you can’t substitute […]
Why Does Consciousness Exist? I mean this question to be a question of biology: what adaptive purpose was served by the evolution of consciousness? Consciousness, like other biological traits, evolved because it contributed to the survival of the organisms that possess it, so there must be an answer to the question of […]
Mind and Behavior Philosophical behaviorism has a curious reputation: on the one hand, it can seem eminently reasonable, on the other, completely wrong. Thus it is natural to be uncomfortably ambivalent about it, veering from acceptance to rejection as the mood strikes. On the side of rejection we have the inverted spectrum, […]
