Introduction: McTaggart’s argument for the conclusion that time does not exist is notoriously hard to understand. C. D. Broad says that when properly interpreted, its main part can be seen to be “a philosophical ‘howler’.” Others see things in it that they regard as true and important, or if not true, then anyway important. But I have not seen any interpretation of it that seems to me to get it exactly right. And I think that it pays to get it right: there are lessons to be learned from consideration of what goes on in it. By way of reminder, McTaggart’s argument has two parts. The first part aims at the conclusion that time does not exist unless the A series exists. The second part aims at the conclusion that the A series does not exist. It follows that time does not exist
A New Argument Against the Existence Requirement
Abstract: It may appear that in order to be any way at all, a thing must exist. A possible – worlds version of this claim goes as follows: (E) For every x, for every possible world w, Fx at w only if x exists at w. Here and later in (R), the letter ‘F’ is used as a schematic letter to be replaced with a one – place predicate. There are two arguments against (E). The first is by analogy. Socrates is widely admired now but he does not exist now. So, it is not the case that for every x, for every time t, Fx at t only if x exists at t. Possible worlds are analogous to times. Therefore, (E) is false (cf., Kaplan 1973: 503 – 05 and Salmon 1981: 36 – 40). For the second argument, replace ‘F’ with ‘does not exist’. (E) then says that for every x, for every possible world w, x does not exist at w only if x exists at w. This is obviously false. Therefore (E) is false (cf., Kaplan 1977: 498). Despite their considerable appeal, these arguments are not unassailable. The first argument suffers from the weakness inherent in any argument from analogy; the analogy it rests on may not.
Against Creationism in Fiction
Abstract: Sherlock Holmes is a fictional individual. So is his favorite pipe. Our pre-theoretical intuition says that neither of them is real. It says that neither of them really, or actually, exists. It also says that there is a sense in which they do exist, namely, a sense in which they exist “in the world of” the Sherlock Holmes stories. Our pre-theoretical intuition says in general of any fictional individual that it does not actually exist but exists “in the world of” the relevant fiction. I wish to defend this pre-theoretical intuition. To do so, I need to defend two claims: that fictional individuals do not actually exist, and that they exist “in the world of” the relevant fiction. The aim of this paper is to defend the first claim.
We Are Living in a Material World (And I am a Material Girl)
Abstract: In this paper I examine the question of whether the characterization of physicalism that is presupposed by some influential anti-physicalist arguments, namely, the so-called conceivability arguments, is a good characterization of physicalism or not. I compare this characterization with some alternative ones, showing how it can overcome some problems, and I defend it from several objections. I conclude that any arguments against physicalism characterised in that way are genuine arguments against physicalism, as intuitively conceived.
Of sensory systems and the “aboutness” of mental states
Summary: The author presents a critique of the classical conception of the senses assumed by the majority of naturalist authors who attempt to explain mental content. This critique is based on neurobiological data on the senses that suggest that they do not seem to describe objective characteristics of the world, but instead act “narcissistically”, so to speak, representing information depending on the specific interests of the organism.
Gender and the Biological Sciences
Summary: Okhrulik offers a feminist critique of biology, a “real” science, to show that it is not just the “soft” social sciences that are affected by bias. She argues that preconceptions can interfere not only in cases of “bad science”, but even when the rules of scientific practice are followed. There is no safeguard against the effects of bias in the context of discovery. Even if theories are rigorously tested to remove bias, some theories might not even be generated and so would not get to the point of being counted as competitors in the testing stage. This is illustrated by a number of case studies. Okhrulik concludes that a diversity of viewpoints is crucial.
Experiments, Simulations, and Epistemic Privilege
Abstract: Experiments are commonly thought to have epistemic privilege over simulations. Two ideas underpin this belief: first, experiments generate greater inferential power than simulations, and second, simulations cannot surprise us the way experiments can. In this article I argue that neither of these claims is true of experiments versus simulations in general. We should give up the common practice of resting in-principle judgments about the epistemic value of cases of scientific inquiry on whether we classify those cases as experiments or simulations, per se. To the extent that either methodology puts researchers in a privileged epistemic position, this is context sensitive.
The Truth Doesn’t Explain Much
Summary: It has sometimes been argued that the covering law model in philosophy of science is too permissive about what gets to count as an explanation. This paper, by contrast, argues that it lets in too little, since there are far too few covering laws to account for all of our explanations. In fact, we rely on ceteris paribus laws that are literally false. Though these are not a true description of nature, they do a good job of allowing us to explain phenomena, so we should be careful to keep those two functions of science separate.
Making Sense of Emergence
Summary: This chapter explores the core thought of the idea of emergentism, that as systems acquire increasingly higher degrees of organizational complexity, they begin to exhibit novel properties which in some sense transcend the properties of their constituent parts, and behave in ways that cannot be predicted on the basis of the laws governing simpler systems. The birth of emergentism can be traced back to John Stuart Mill and his distinction between “heteropathic” and “homeopathic” laws. Academic philosophers contributed to the development of emergence and the attendant doctrines of emergentism, but it is interesting to note that the fundamental idea seems to have had a special appeal to scientists and those outside professional philosophy. In spite of this, emergentism failed to become a visible part of mainstream philosophy of science because philosophy of science was, at the time, shaped by positivist and hyper-empiricist views that dominated Anglo-American philosophy.
Empty Ethics: The Problem with Informed Consent
Abstract: Informed consent is increasingly heralded as an ethical panacea, a tool to counter autocratic and paternalistic medical practices. Debate about the implementation of informed consent is constricted and polarised, centring on the right of individuals to be fully informed and to freely choose versus an autocratic, paternalistic practice that negates individual choice. A bioethical framework, based on a principle-led form of reductive/deductive reasoning, dominates the current model of informed consent. Such a model tends to abstract the process of consent from its clinical and social setting. By fleshing out the social process involved when patients and healthy volunteer subjects consent to take part in clinical drug trials, this paper attempts to address the problem arising from the current ’empty ethics’ model. My arguments are substantiated by qualitative interview data drawn from a study I conducted on the process of consent as experienced by participants in clinical drug trials.
