Steven Hales constructs a novel argument against the possibility of presentist time travel called the suicide machine argument. Hales argues that if presentism were true, then time travel would result in the annihilation of the time traveler. But such a consequence is not time travel, therefore presentism cannot allow for the possibility of time travel. This paper argues that in order for the suicide machine argument to succeed, it must make (at least) one of two assumptions, each of which beg the question. The argument must either assume that the sequence of moments is invariant, or that time travel requires distinct, co-instantiated moments. Because the former disjunct assumes that presentist time travel is impossible and the latter assumes that presentism is impossible, the suicide machine argument fails.

My topic is two-fold: a reductive account of expertise as an epistemic phenomenon, and applying the reductive account to the question of whether or not philosophers enjoy expertise. I conclude, on the basis of the reductive account, that even though philosophers enjoy something akin to second-order expertise (i.e. they are often experts on the positions of other philosophers, current trends in the philosophical literature, the history of philosophy, conceptual analysis and so on), they nevertheless lack first-order philosophical expertise (i.e. expertise on philosophical positions themselves such as the nature of mind, causality, normativity and so forth). Throughout the paper, I respond to potential objections.

In this paper, I defend my original objection to Hales’ suicide machine argument against Hales’ response. I argue Hales’ criticisms are either misplaced or underestimate 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.

My purpose, in this paper, is to defend the claim that the fine-tuning argument suffers from the poor design worry. Simply put, the worry is this: if God created the universe, specifically with the purpose of bringing about moral agents, we would antecedently predict that the universe and the laws of nature, taken as a whole, would be well-equipped to do just that. However, in light of how rare a life-permitting universe is, compared to all the ways the universe might be have been life-prohibiting given the laws of physics, strongly suggests that the universe was poorly designed for that purpose. This casts doubt on the claim that God has much to do with designing the universe. First, I introduce the fine-tuning argument, and second, I explain and defend the poor design worry against objections that, while apparently compelling, I argue are misleading
