Meta-ethics on the Brain
Last night I had what might actually be the strangest dream ever. It was much weirder than hilzoy's now-famous (among philosophy bloggers, at least) synthetic a priori dream. In my dream, some space aliens discovered that platonism was false. They were very disturbed by this because, they thought, without platonic objects, there was nothing to serve as the ontological ground for moral facts. So the aliens convened a galactic council, and held a sort of lottery. Earth lost the lottery, so the aliens were rounding up all the humans and putting them into a simulation. In the simulation, the humans...

Philosophers' Carnival 107
The 107th Philosophers' Carnival
is now up at Philosophy of Brains
, with a link to my post, "Morality as a System of Assertoric Imperatives"
. Also of interest is Gary Williams' "The Myth of Sensory Immediacy - Why Berkeley Was Wrong"
, which argues that modern understanding of the neuro-psychology of perception disproves the sense data theory and thus deprives Berkeley of his starting point.

Quote of the Day: Turbayne on Alleged Refutations of Berkeley
The argument [for idealism] achieves [a proof of the external world] in a most ingenious yet simple way, by accepting the sceptical conclusion of one such as Hylas, that all we can ever know of the external world is certain ideas or appearances, and then admitting, as any consistent empiricist must, that these appearances are real. After all, it is a jest to hold, as do the philosophers, that the things we see and touch are mere illusions.  This final step illuminates the irony inherent in Dr. Johnson's notorious ostensive refutation of Berkeley's 'ingenious sophistry', by exclaiming while 'striking...

Kantian Ethics Simplified
It is probably a safe bet that no view which has ever been successfully explained in a blog post can correctly be attributed to Kant. I won't try to falsify that claim in this post. What I will try to do is to present a sketch of a simple (probably too simple) moral theory that shows why I find Kantian ethics attractive. The fundamental principle of this ethical theory is the following definition: Wrongness =df. the property an action has iff it is the direct result of a practical judgment whereby the agent is committed to a practical contradiction. An...

Morality as a System of Assertoric Imperatives
I recently read Philippa Foot's paper "Morality as a System of Hypothetical Imperatives" for an ethics class. The paper, as the name suggests, puts forward the view (which Foot has since rejected) that the imperatives of morality are merely hypothetical and not, as Kant had argued, categorical. What this means is that morality tells us how we should act if we want certain things, such as justice and the general happiness of humanity. As Foot recognizes, an untoward consequence of this view is that, if it is true, we can't sensibly tell people that they should want justice or the...

Quote of the Day for Good Friday
In honor of Good Friday, I offer the following original translation of some excerpts from the Gospel of John: In the beginning Reason was - Reason was directed toward God, and Reason was God. He was directed toward God in the beginning. All things came about through Him, and none of the things that came about came about apart from Him. In Him was life, and the life was the light of human beings. The light shines in the darkness, and the darkness does not grasp it. ... [Reason] was the true light, which, coming into the world, enlightens every...
