PHILOSOPHY

Like so many of my peers, I’ve been afflicted by the bad habit of arguing about utilitarianism.

A review of the thought experiments in Reasons and Persons by Derek Parfit (part one)

You live with a group of utterly rational and self-interested people on an island, gathering coconuts to survive. Tired of working so hard, Alice builds a machine and implants it in her brain. This machine leaves her rational except when...
Are ethics all a lie?

If we only believe in ethics because of evolution, does that mean ethics are a lie?

Some people claim ethics aren’t practical. Others make a grim philosophical argument:

Pragmatic reasons to believe in formal ethics

Some situations where formal ethics are really needed for practical problems in real life.

Here’s a “low-brow” take on ethics that’s worth taking seriously:

It's hard to use utility maximization to justify creating new sentient beings

The ethical theory of Utilitarianism applies to many situations, but runs into problems when choices might create new beings.

Cedric and Bertrand want to see a movie. Bertrand wants to see Muscled Duded Blow Stuff Up. Cedric wants to see Quiet Remembrances: Time as Allegory. There’s also Middlebrow Space Fantasy. They are rational but not selfish - they care...
