Nicolas Langlitz: Psychedelics and Philosophy | Who Shaves the Barber? #45

Psychedelic substances, such as psilocybin mushrooms, LSD, and ayahuasca, do much more than generate sensory hallucinations. Users often come away with a sense of having gained deep insight into the nature of reality – even if what that insight is, and what is so special about it, can be hard to communicate. Anthropologist Nicolas Langlitz associates it with the “perennial philosophy” – an old idea, popularized by Aldous Huxley, that all world religions communicate the same basic truth. Years after writing the book The Perennial Philosophy, Huxley tried mescaline and LSD and became convinced that psychedelics provide a shortcut to the kinds of mystical experiences that would put us in touch with that basic reality – what he called the “world mind”. Langlitz is skeptical that psychedelics really do communicate some kind of metaphysical truth. In this interview, we discuss what psychedelics do reveal, if anything, and what the relationship is between experience and knowledge.

Jc Beall: Logic of Christ | Who Shaves the Barber? #44

Jc Beall

Christ is a walking contradiction. He is both fully human and fully divine. Indeed, he is both mutable and immutable. According to classical logic, the existence of a true contradiction would imply that everything is the case, no matter how absurd. And so, theologians and Christian metaphysicians have worked for centuries to conceptually make sense of Christ’s dual nature in a way that avoids contradiction.

Philosopher and logician Jc Beall argues that these efforts have been motivated by a naive understanding of logic. There are “subclassical” logics – that is, logics weaker than classical logic – in which contradictions do not entail every arbitrary conclusion. And these aren’t ad-hoc constructions. Beall argues that one subclassical logic – called First Degree Entailment (FDE) – is, in fact, the correct account of logical consequence, for reasons independent of the Christian problem. Beall covers the basics of how FDE works and why it is the universal or “basement-level” consequence relation. This allows us to have our cake and eat it too: we may take Christ to be, quite literally, both mutable and not mutable, at the same time and in the same respect. This isn’t just appealing for its simplicity. Beall suspects that it is essential to Christ’s role that he be literally contradictory.

Jason Lee Byas: Against Criminal Justice | Who Shaves the Barber? #43

Download this episode / Watch on YouTube / RSS Feed / iTunes

What gives some people the right to put others in prison? Is prison – and the criminal justice system generally – an ethically permissible method for dealing with criminality?

Individualist anarchist and prison abolitionist Jason Lee Byas goes over the common justifications for the prison system and explains why none of them succeed. Specifically, he covers the doctrines of retributivism (specifically desert retributivism and expressive retributivism), deterrence, rehabilitation, and rights forfeiture, arguing against each. In place of prison, Byas proposes a tort system of restitution. Monetary restitution may not be sufficient to right the wrong of a crime, says Byas; but it is all that the law should mandate, leaving other desired correction or compensation up to community-based initiatives (Byas cites restorative justice as an example of the sort of institutions that can take the place of those corrective aspects of criminal justice that retribution does not address). Byas also explains how a system of monetary restitution can get around problems of class-based inequality (for example, if someone is so rich that they don’t mind having to pay to commit a crime, or if someone is so far in debt that another dent wouldn’t matter). Finally, he explains how violent offenders who pose an “ongoing threat” might be handled in his preferred system.
