Could you be a brain in a vat, or be living in a simulated or virtual reality? Could you live a meaningful, valuable existence even if you were?

The Philosophy of Black Mirror's White Bear | Rebecca Tuvel

Black Mirror's episode, White Bear, is full of interesting philosophical problems. Are you still responsible for a crime you committed even if you've lost your memory of that crime? Do you persist through time despite amnesia? And what are the limits of justified punishment for horrendous crimes?

David Benatar on the Israel Palestine Conflict

David Benatar on the Israel Palestine Conflict

Are Jews entitled to their own homeland?  Is the Israeli response to the massacre of civilians perpetrated by Hammas on October 7th justified? Should there be a ceasefire? 

David's Article in Quillette: https://quillette.com/2023/10/21/its-not-the-occupation/ 


Raja Halwani wrote to us about Jason's exposition of his view at 38:50. Here is Raja's clarification:

**I wanted to clarify a point that Jason made during the interview with David Benatar. Jason asked Benatar what he thought of the view that “the view is that the Gazans are an oppressed people. They’ve been oppressed for so long that they’ve acted out of desperation. And there’s only two options that they have.” Jason goes on to say that I have defended the view that “the Gazans are an oppressed people who only have two options. The one option is to die and the other option is to attack, to attack Israel in order to secure some sort of freedom. Those are its only two options. And so ... Raja takes the view that if Hamas were to lay down its arms, then it’s just a slow death for the Gazans. That’s, that would be the future of Gaza.”

However, I did not make this claim about having only two options, nor would I, because it reads as a justification of killing civilians, especially given the context of the Hamas attacks of October 7 (and other attacks against Israelis). It reads as a justification because if death is one of only two options, then the second, to attack, seems permissible. The last sentence in Jason’s question, about Hamas laying down its arms, seems to especially imply this (though Jason did not intend to make me come out as justifying Hamas’s actions).

Jason attributes this view to me based on something I wrote in my blog (as he explained to me in personal correspondence). Here is the specific passage on which Jason bases his attribution:

People are quick to condemn Hamas for the evil that it has wrought, but they are as quick to neglect that Hamas acts out of sheer desperation, out of the sheer desire, no matter how steep the price, to score a victory against Israel, a country whose military might not even its prime ministers fully comprehend, and out of the sheer hopelessness of the slow death that their people has been dying. Although to explain this is not to justify it, I also ask the reader: What options do the Palestinians have? What do you advise them to do? Their lives are going nowhere. Peace initiative after peace initiative has failed them (and, to add insult to injury, they are blamed for the failure). No Palestinian state has emerged, and none is likely to given the current map (just look and see whether a state can be built out of the Swiss cheese that is the West Bank). Their tunnel has been long and with no light at its end. So what should they do? They ought to sit still and “take it like a man.” To suck it up. To bear the unfair burden of history. We have to tell them, “Misfortune has fallen upon you, and you may not extricate yourselves from it by killing civilians. Even as you yourselves die, slowly, surely, with no justification, and with barely an explanation, you may not take the lives of the civilians of your enemy. This is the noble way.”

Clearly, the passage is a bitter one about Palestinian loss and oppression, but it is as clearly morally ruling out the option of killing civilians. So even though Hamas might take up arms against civilians, this is not a morally viable options for Gazans or Palestinians in general. Hence, insofar as Jason’s question attributes to me a justification of attacks on civilians, this clarification should clarify that this is not my position.**

Pornography and Exploitation | Holly Lawford-Smith

Are women generally exploited in pornography? Even in cases where women report that their pornography career is empowering, have they nevertheless been degraded? And if heterosexual pornography undermines women’s dignity, is this true of gay male pornography too?

Imagine There’s No Gender | Holly Lawford-Smith (with Raja Halwani)

Imagine There’s No Gender | Holly Lawford-Smith (with Raja Halwani)

Would the world be better if we didn’t recognize genders?


In such a world, there would be males and females, but nothing associated with what it means to be male or female other than biological facts. Men and women would be equally likely to be social leaders. And there would be no stereotypically male or female behavior.


In this world, there’d be true sex equality, and, it seems, no need for trans activists. Should we fight for such a world?

Stephen Kershnar on the Impossibility of Responsibility

Stephen Kershnar on the Impossibility of Responsibility

Kershnar presents a dilemma: we’re responsible for our decisions because they’re caused by our psychology. But do we choose our psychology? If we do, then it seems that choice couldn’t have been a morally responsible choice, since our psychology didn’t choose it. But if we didn’t choose our psychology, then we can’t be responsible for the choices that come from our psychology.
