Logos & Episteme

In this paper, I defend my original objection to Hales’ suicide machine argument against Hales’ response. I argue Hales’ criticisms are either misplaced orunderestimate the strength of my objection; if the constraints of the original objection are respected, my original objection blocks Hales’ reply. To be thorough, I restate an improved version of the objection to the suicide machine argument. I conclude that Hales fails to motivate a reasonable worry as to the supposed suicidal nature of presentist time travel.

In a series of recent papers Stephen Kearns and Daniel Star argue that normative reasons to φ simply are evidence that one ought to φ, and suggest that“evidence” in this context is best understood in standard Bayesian terms. I contest this suggestion.
