In this thesis, I will explore the epistemological evolutionary debunking arguments in meta-ethics. I will defend these arguments by accomplishing two tasks: I will offer the best way to understand the EDA and I will also respond to two strongest objections to the EDA. Firstly, in Part I of this thesis, I will offer my account of how the EDA should be best formulated. I will start from how evolution has significantly influenced our moral beliefs. I will then explain why, (...) due to their evolutionary origin, our moral beliefs are not tracking the moral truth reliably. Furthermore, I will argue that the fact that our moral beliefs are not tracking the moral truth also provides an undercutting and a higher-order defeater for those beliefs. As a result, I will conclude that the epistemic status of our moral beliefs is undermined because of these two kinds of defeaters. Secondly, in Part II of this thesis, I will turn my attention to the two strongest objections to the EDA – the Conceptual Truth Objection and the Third Factor Objection. I will first offer two responses to the Conceptual Truth Objection and, based on these two responses, I will argue that the Conceptual Truth Objection fails as a challenge to the EDA. I will then also argue that there currently doesn’t exist an acceptable version of the Third Factor Objection and it is also unlikely that such a version could be constructed in the future. I will finally conclude that both objections are problematic and they are thus unable to give us reason to doubt the EDA. (shrink)

The naturalistic fallacy according to Moore and its relation to Hume will be analyzed for an exposition both clear and updated in contemporary formal logics, which will denounce its limited scope in current metaethics. I’ll identify the origins of the expression naturalistic fallacy in Moore and atempt to refne its meaning and use, contrasting its relationship to the open-question argument and Hume’s Law. Its application is identifed in four aspects: invalidly as the openquestion argument for not establishing a metaphysical connection (...) and providing false cognates, and validly as a categorical error, a misidentifcation error and an inferential error; this last one relatable with Hume’s Law as a procedural argumentation error. Brief applications show the limits of the naturalistic fallacy in that, contradictorily, it isn’t a fallacy but by one of its uses, as well as not rebuting every naturalistic theory (as hedonism and utilitarianism) besides being also an argument in favor of some (non-cognitivists).

Normative naturalism is primarily a metaphysical doctrine: there are normative facts and properties, and these fall into the class of natural facts and properties. Many objections to naturalism rely on additional assumptions about language or thought, but often without adequate consideration of just how normative properties would have to figure in our thought and talk if naturalism were true. In the first part of the paper, I explain why naturalists needn’t think that normative properties can be represented or ascribed in (...) wholly non-normative terms. If so, certain prominent objections to normative naturalism fail. In the second part, I consider the objection that normative properties are “just too different” from (other) natural properties to themselves be natural properties. I argue that naturalists have no distinctive trouble making sense of thought and talk involving forms of “genuine” or “authoritative” normativity which can drive a non-question-begging form of the objection.

The buck-passing account of value involves a positive and a negative claim. The positive claim is that to be good is to have reasons for a pro-attitude. The negative claim is that goodness itself is not a reason for a pro-attitude. Unlike Scanlon, Parfit rejects the negative claim. He maintains that goodness is reason-providing, but that the reason provided is not an additional reason, additional, that is, to the reason provided by the good-making property. I consider various ways in which (...) this may be understood and reject all of them. So I conclude that buck-passers cannot reject the negative claim. (shrink)

Are values objective or subjective? To clarify this question we start with an overview of the main concepts and debates in the philosophy of values. We then discuss the arguments for and against value realism, the thesis that there are objective evaluative facts. By contrast with value anti-realism, which is generally associated with sentimentalism, according to which evaluative judgements are grounded in sentiments, value realism is commonly coupled with rationalism. Against this common view, we argue that value realism can be (...) combined with sentimentalism, and we suggest that a plausible account, which we call ‘sentimental realism’, and according to which evaluative judgements are closely related to emotions, can be developped.

This Thesis reconsiders the prospects for an approach to global justice centring on the proposal that every human being should possess a certain bundle of goods, which would include certain members of a distinctive category: the category of capabilities. My overall aim is to present a clarified and well-developed framework, within which such claims can be made. To do this, I visit a number of regions of normative and metanormative theorising. I begin by introducing the motivations for the capability approach, (...) and clarifying some of its most distinctive features. Next, I focus on Martha Nussbaum's version of the approach, and identify several problems therein. The most important concerns epistemology, and especially the challenges that constructivist theories pose. The middle part of the Thesis presents an alternative, based on the work of John McDowell, which I argue has superior prospects. Then, I turn to two further problems: that of making sense of the universalistic aspirations of cosmopolitanism, and that of integrating the microscopic prescriptions of ethics with the macroscopic analyses of political philosophy. Using the Aristotelian interpretation of its core framework that I have developed, I conclude that the capability approach can provide compelling answers to important questions about global justice.

This dissertation is a defence of metaphysical ethical naturalism according to which there is a moral reality which is part of the natural world. The implication of this view is that moral properties, such as moral goodness, justice, compassion and so forth are part of the natural world, and inquiries concerning these moral entities are conducted in similar empirical ways of reasoning to that in which scientific inquiries are conducted. I defend metaphysical ethical naturalism by a variety of explanationist argument (...) in the tradition of Cornell realism. I examine preceding proposals for this argument, and focus on one version of it, which I call ‘the abductive argument for moral realism’. Although there was a suggestion about the abductive argument, the argument has not been discussed enough in the literature. This dissertation is a defence and discussion about the abductive argument which has not been properly examined. The defence of the argument requires the examination of how first-order ethical theory can be developed in the similar empirical ways scientific theories are developed. This will be an attempt to show the analogy between scientific inquiries and ethical inquiries. Describing the analogy between science and ethics, I will argue that the analogy can be best explained in terms of the approximate truth of normative theory which implies the existence of mind-independent natural moral properties.
