In 2002, American paleontologist Stephen Jay Gould paid a surprising tribute to Nietzsche’s evolutionism. I explain this critical affinity, which Daniel Dennett had already pointed out in 1995, focusing on three aspects. First, I show how it allows Gould to dispense with the dualistic separation between natural sciences and humanities and social sciences, in which Dennett tries to confine him. Second, I explain how it allows for promising and unsuspected ways to re-examine Nietzsche’s Will to Power hypothesis. Finally, I argue that it provides solid grounds for Nietzsche’s criticism of Darwinism.

According to standard Creationism about fictional characters, each fictional character is created by its single author independently, or created by its co-authors cooperatively, or created by its independent authors independently. I argue that standard Creationism faces the Creator-Determining Problem. I propose a non-standard form of Creationism, i.e., Conjunctive Creationism, according to which each fictional character is conjunctively created. I argue that Conjunctive Creationism does not face the Creator-Determining Problem. By responding to four potential worries, I provide a further defense. My conclusion is that Conjunctive Creationism is a more promising form of Creationism.

It is sometimes claimed that conciliatory views on disagreement ultimately lead to either global or widespread scepticism. This is deemed to be a real problem for conciliationism either because scepticism of either kind is patently untenable or because it poses a serious threat to our intellectual and social lives. In this paper, I first argue that the alleged untenability of both types of scepticism is far from obvious and should therefore be established rather than taken for granted. Then, I show that those who reject both types of scepticism because of the threat they pose surprisingly confuse pragmatic reasons with epistemic reasons.

Epigenetics reveals the biological mechanisms underlying the reproduction and even the transmission of social inequalities in health. It also emphasizes the complexity of factors involved in the development of some diseases. This complexity raises new difficulties for theories of justice. Is the equal opportunities theory the most appropriate to solve these difficulties? I demonstrate that epigenetics requires a multifactor model of justice—one that is grounded on principles of fairness, impartiality, and environmental and intergenerational justice. Depending on the point of view assumed (i.e., individual, population-based, or intergenerational), the relevant principle of justice is different.

In this paper, I defend a metaethical position described as ‘actual agreement contractualism’: the view that norms arise from actual attempts to arrive at legitimate terms for social cooperation among all those affected. I distinguish the actual agreement approach from hypothetical approaches to contractualism, and defend the former against objections from Thomas Scanlon, in particular. The attractiveness of a focus on actual agreements, I argue, is seen in the way it resolves problems internal to the hypothetical approach as well as in its implications for the purpose of moral theory and for the obligation to justify our actions to others.
