In this paper, we defend Lucretian Presentism. Although the view faces many objections and has proven unpopular with presentists, we rehabilitate Lucretianism and argue that none of the objections stick.

In addressing the Lucretian symmetry problem, the content-based approach attends to the difference between the contents of the actual life and those of relevant possible lives of a person. According to this approach, the contents of a life with an earlier beginning would substantially differ from, and thus be discontinuous with, the contents of the actual life, whereas the contents of a life with the same beginning but a later death would be continuous with the contents of the actual life. (...) In this paper, I examine two versions of the content-based approach: the identity account and the preference account. The identity account holds that, in the sense of identity which is relevant to the evil of nonexistence, the subject of the actual life, though identical to the person in the life with a later death, is distinct from the subject of the life with an earlier beginning. The preference account maintains that, given one’s attachments to actual particulars, a life with an earlier beginning is not rationally preferable to one’s actual life, whereas a life with a later death is. I argue that each version of the content-based approach is implausible, while discussing some of the complications that face each of them. (shrink)

According to the presentist, it is always the case that the only existing objects are those that exist at the present time, and the only properties and relations that are instantiated are those that are instantiated at the present time. The truth-supervenes-on-being thesis (TSB) is that there can be no difference in what is true without a corresponding difference in what exists and in what properties and relations are instantiated. The truth-supervenes-on-being objection says that presentism cannot accommodate TSB. Lucretianism (...) is the thesis that the world instantiates irreducibly past-tensed properties. Though not popular, it is not entirely uncommon for presentists to endorse Lucretianism as a means to respond to the truth-supervenes-on-being objection. Defenses of Lucretianism itself are still less common. Appropriately up-to-date defenses are lacking altogether. I take up such a defense, arguing that the attacks on Lucretianism fail, and that there is, therefore, no compelling truth-supervenes-on-being objection to presentism. (shrink)

It seems that people typically prefer dying later to dying earlier. It also seems that people typically do not prefer having been created earlier to having been created later. Lucretius’ Puzzle is the question whether anything typically rationally recommends having a preference for dying later to dying earlier over having a preference for having been created earlier to having been created later. In this paper, I distinguish among three ways in which Lucretius’ Puzzle can be understood and say how I (...) think they ought to be answered. (shrink)

Hume’s famous and influential contributions to the philosophy of religion pursue two broad themes that have deep links with his general sceptical and naturalistic commitments throughout his philosophy as a whole.1 The first is his sceptical critique of the philosophical arguments and doctrines of various (Christian) theological systems. The second is his naturalistic account of the origins and roots of religion in human nature. Taken together, these two themes serve to advance Hume’s “Lucretian mission”, which was to discredit and dislodge (...) the role of religion in human life. In this paper I consider the criticism that Hume’s entire Lucretian mission is fundamentally misguided and misconceived as judged in terms of his own claims and hypotheses concerning religion. More specifically, it may be argued that if Hume is right about the foundations of religion in human nature and the human predicament, then his Lucretian mission is neither wise nor achievable. His project is, in other words, both theoretically self-refuting and practically self-defeating. Drawing from Hume’s writings on this subject, I will suggest a set of replies and responses to these criticisms. (shrink)

In addressing the Lucretian symmetry problem, the temporal bias approach claims that death is bad because it deprives us of something about which it is rational to care (e.g., future pleasures), whereas prenatal nonexistence is not bad because it only deprives us of something about which it is rational to remain indifferent (e.g., past pleasures). In a recent contribution to the debate on this approach, Miguel and Santos argue that a late beginning can deprive us of a future pleasure. Their (...) argument is based on the claim that for birth or death to deprive a person of any value in life, the historically closest counterfactual situation that contains the value is such that the person begins to exist earlier or dies later. This is what they call the Historical Condition. However, the Historical Condition is untenable for several reasons. First, this condition substantially weakens the explanatory capacity of the deprivation account because it implies that most ordinary sorts of pleasures are not deprived by death. In addition, the Historical Condition is vulnerable to counterexamples. In particular, what they offer as a standard case of the deprivation of future pleasure due to a late beginning (what they call Seeing The Beatles), or some of its variants, can be used to falsify this condition. Finally, the Historical Condition is theoretically indefensible because it is based on a faulty analysis of deprivation. (shrink)

Death can be bad for an individual who has died, according to the “deprivation approach,” by depriving that individual of goods. One worry for this account of death’s badness is the Lucretian symmetry argument: since we do not regret having been born later than we could have been born, and since posthumous nonexistence is the mirror image of prenatal nonexistence, we should not regret dying earlier than we could have died. Anthony Brueckner and John Martin Fischer have developed a response (...) to the Lucretian challenge by arguing that it is rational to have asymmetric attitudes toward posthumous and prenatal nonexistence. Recently, Jens Johansson has criticized the Brueckner/Fischer position, claiming that it is irrelevant whether it is actually rational to care about future pleasures but not past pleasures. What matters, according to Johansson, is whether it would be rational for us to care about past pleasures had we come into existence earlier. In this paper, I add to the conversation between Johansson and Brueckner/Fischer by suggesting a way to defend the latter side’s position in a way that has not yet been suggested. I do this by considering a suggestion of Johansson’s for interpreting the Brueckner/Fischer position and by arguing that Johansson’s worry for the position I consider is actually incoherent.

Here I respond to Anthony Brueckner and John Martin Fischer’s “The Evil of Death: A Reply to Yi.” They developed an influential strategy in defense of the deprivation account of death’s badness against the Lucretian symmetry problem. The core of their argument consists in the claim that it is rational for us to welcome future intrinsic goods while being indifferent to past intrinsic goods. Previously, I argued that their approach is compatible with the evil of late birth insofar as an (...) earlier birth would have generated more goods in the future. In reply, Brueckner and Fischer argue that my critique fails to appreciate an important aspect of their thought experiment, which aims only to show that the deprivation of past goods per se is not bad for us. Thus, purportedly, my critique poses no threat to their view. Here I argue that since the deprivation account explains the evil of death with recourse to how one’s life would have fared had one lived longer, it ought to respond to the symmetry problem with reference to how one’s life would have fared had one been born earlier. However, it is not generally true that the life one would have had with an earlier birth is not preferable to one’s actual life, because in many cases such a life would contain more future goods.

In his book On the Nature of Marx’s Things Jacques Lezra inherits another Marx and another materialism. It is an aleatory materialism: a materialism of the dynamic contingency of Marx and his “things”. This “subterranean current” of aleatory materialism is excavated by Lezra in his swerve through the letters, notebooks, and “private notes” of a young Marx working on his doctorate thesis. Following Lezra’s necrophilological thread –which encounters Lucretius and his “things”– we find that, in a parallel fashion, Marx is (...) also searching for a concept of science in his dissertation. This is what here is tentatively called a science of contingency. This science – though not in the usual disciplinary sense– opens the possibility of an alliance with Karen Barad’s performative materialism that displaces the humanism of the “new materialisms” by thinking alongside another science of contingency, also of a certain Lucretian inheritance, and which Marx did not get to think: quantum mechanics. -/- -- -/- En su libro On the Nature of Marx’s Things Jacques Lezra hereda otro Marx, y otro materialismo. Un materialismo aleatorio, un materialismo de la contingencia dinámica de Marx y sus “cosas”. Tal “corriente subterránea” del materialismo aleatorio es excavada por Lezra en su desvío por las cartas, cuadernos y notas “privadas” de un joven Marx que trabajaba en su tesis de doctorado. Siguiendo el hilo necrofilológico de Lezra, que se topa con Lucrecio y sus “cosas,” encontramos que, paralelamente, Marx también busca un concepto de ciencia en su tesis: lo que tentativamente nombramos ciencia de la contingencia. Ciencia, no ya disciplinaria, que abre la posibilidad de una alianza con el materialismo performativo de Karen Barad que desplaza el humanismo de los “nuevos materialismos” desde una reflexión critica que piensa a la par de otra ciencia de la contingencia, también de cierta herencia lucreciana, con la cual Marx no llegó a pensar: la mecánica cuántica.

Ernst Haeckel and Emil du Bois-Reymond were the most prominent champions of Darwin in Germany. This essay compares their contributions to popularizing the theory of evolution, drawing special attention to the neglected figure of du Bois-Reymond as a spokesman for a world devoid of natural purpose. It suggests that the historiography of the German reception of Darwin’s theory needs to be reassessed in the light of du Bois-Reymond’s Lucretian outlook.

ABSTRACT This article is a response to 'Fear of death and the symmetry argument', in this issue. In that article, the author discusses the above Lucretian symmetry argument, and proposes a view that justifies the existing asymmetry in our attitudes towards birth and death. I begin by distinguishing this symmetry argument from a different one, also loosely inspired by Lucretius, which also plays a role in the article. I then describe what I take to be the author's solution to the (...) original symmetry argument and explain why I am unpersuaded by it. (shrink)

In his version of atomism, Lucretius made explicit reference to the concept of an intrinsic declination of the atom, the atomic swerve (clinamen in Latin), stressing that the time and space of the infinitesimal atomic vibration is uncertain. The topic of this article is the Epicurean and Lucretian arguments in favour of the swerve. Our exposition of the Lucretian model of the atomic clinamen will present and elucidate the respective considerations on the alleged role of the swerve in the generation (...) of free-action. (shrink)
