Objectivity and reliability

Scanlon’s Being Realistic about Reasons is a beautiful book – sleek, sophisticated, and programmatic. One of its key aims is to demystify knowledge of normative and mathematical truths, realistically construed – i.e. construed, roughly, as being true relevantly independent of minds and languages, when interpreted at face-value. In this article, I develop an epistemological problem that Scanlon fails to explicitly address. I argue that his ‘metaphysical pluralism’ can be understood as a response to that problem. However, it resolves the problem only if it undercuts the objectivity of normative and mathematical inquiry.     

Shareability and Objectivity

The aim of this essay is to work toward a better understanding of the metaphysical status of meaning by critically examining two arguments – one is Plato’s, the second Frege's – along the following lines:

• P1: Meaning is shared in successful communication.
• P2: Successful communication occurs.
• C: Therefore, meaning is objective.

The first two sections are dedicated to expounding and justifying the two premises; the third distinguishes some relevant notions of objectivity. Sections four and five discuss the arguments of Plato and Frege, with a view to paring away some potentially misleading ways of speaking, and avoiding any slippage among distinct senses of ‘objective’. The sixth section analyses the content of the claim that abstract objects exist. I conclude by criticizing some assumptions, and drawing some morals, about the place of meaning in one's metaphysical world‐view.     

From Aperspectival Objectivity to Strong Objectivity: The Quest for Moral Objectivity

Sandra Harding is working on the reconstruction of scientific objectivity. Lorraine Daston argues that objectivity is a concept that has historically evolved. Her account of the development of “aperspectival objectivity” provides an opportunity to see Harding's “strong objectivity” project as a stage in this evolution, to locate it in the history of migration of ideals from moral philosophy to natural science, and to support Harding's desire to retain something of the ontological significance of objectivity.     

Objectivity in ethics

In this paper I have tried to clarify the meaning of two very different sets of characteristics which philosophers have had in mind when they claimed that ethical terms were objective. I gave a very tentative answer to the question whether it is true to say that, in any of the distinguished senses, ethical statements are objective. Lastly, I indicated how the failure to make the distinction I draw was responsible for a number of confusions and unnecessary difficulties. More precisely, in (1) I defined the first set of the characteristics in question, which together I have called solidity; in (2) I give reasons why it is misleading to claim that ethical statements are solid and also misleading to claim they are not; in (3) I defined the second set of these characteristics, namely, proper contentiousness and proper complexity; in (4) I explained what I thought were the fundamental differences between these two sets of characteristics; in (5) I suggested that the solidity of an expression is normally a good reason for holding that the expression is properly contentious and properly complex; in (6) I claim that the failure to understand (4) and, therefore, also (5) leads to the following errors: (a) that, if an expression is solid, it must be properly contentious and properly complex; that, if an expression is non-solid, it must be either properly contentious and properly simple, or properly non-contentious. (5) That, if an expression is properly contentious and properly complex, it must be solid; if it is properly contentious and properly simple or if it is properly non-contentious, then it must be non-solid; and lastly in (7) I have mentioned some common reasons for holding that ethical expressions have one or the other of the above-mentioned characteristics.     

Formulating Moral Objectivity

Objective moral facts are supposed to be independent from us, but it has proven difficult to provide a clear account of this independence condition. Objective moral facts cannot be overly independent of us, as even an objective morality would depend, in important respects, on features of us. The challenge is to respect these moral mind-dependencies without inappropriately counting too many moral facts as objective. In this paper, I delineate and evaluate several different versions of the independence condition in moral objectivity. I raise problems for these ways of formulating moral objectivity and then develop a better account of moral objectivity, one that avoids the pitfalls of other proposals.     

Autonomy and Objectivity of Science

This article deals with the problematic concepts of the rational and the social, which have been typically seen as dichotomous in the history and philosophy of science literature. I argue that this view is mistaken and that the social can be seen as something that enables rationality in science, and further, that a scientific community as well as an individual can be taken as an epistemic subject. Furthermore, I consider how scientific communities could be seen as freely acting and choosing agents. Fundamentally, this boils down to the question whether we accept the voluntarist conception of human beings, one consequence of which is that scientists possess, in principle, the capacity for deliberative reflection and choice. If this is accepted, we can talk about the degrees of autonomy that communities possess. I also examine what kinds of decisions an autonomous community should make in order to produce objective knowledge. My suggestion is that objectivity be understood as intersubjectivity: a view is objective when it has been exposed to critical reflection from various points of view, and due to this, transcends subjective idiosyncrasies.     

The Knowledge Argument and Objectivity

In this paper I argue that Frank Jackson’s Knowledge Argument is better considered not as an argument against physicalism, but as an argument that objective theories must be incomplete. I argue that despite the apparent diversity of responses to the knowledge argument, they all boil down to a response according to which genuine epistemic gains are made when an individual has an experience. I call this the acquaintance response. I then argue that this response violates an intuitive stricture on the objectivity of theories. Therefore, the knowledge argument does show that objective theories cannot provide a complete understanding of the world. The result, however, is that both objective dualism and objective physicalism are refuted by the argument. In the end it is suggested that the notion of “subjective physicalism” is one that should be pursued.     

Truth and Objectivity in Perspectivism

I investigate the consequences of Nietzsche's perspectivism for notions of truth and objectivity, and show how the metaphor of visual perspective motivates an epistemology that avoids self-referential difficulties. Perspectivism's claim that every view is only one view, applied to itself, is often supposed to preclude the perspectivist's ability to offer reasons for her epistemology. Nietzsche's arguments for perspectivism depend on “internal reasons”, which have force not only in their own perspective, but also within the standards of alternative perspectives. Internal reasons allow a perspectivist argument against dogmatism without presupposing aperspectival criteria for theory choice. Nietzsche also offers “internal” conceptions of truth and objectivity which reduce them to a matter of meeting our epistemic standards. This view has pluralistic implications, which conflict with common sense, but it is nevertheless consistent and plausible. Nietzsche's position is similar to Putnam's recent internalism, and this is due to their common Kantian heritage. This revised version was published online in August 2006 with corrections to the Cover Date.     

Modal Objectivity1

It is widely agreed that the intelligibility of modal metaphysics has been vindicated. Quine's arguments to the contrary supposedly confused analyticity with metaphysical necessity, and rigid with non‐rigid designators.² But even if modal metaphysics is intelligible, it could be misconceived. It could be that metaphysical necessity is not absolute necessity – the strictest real (non‐epistemic, non‐deontic) notion of necessity – and that no proposition of traditional metaphysical interest is necessary in every real sense. If there were nothing otherwise “uniquely metaphysically significant” about metaphysical necessity, then paradigmatic metaphysical necessities would be necessary in one sense of “necessary”, not necessary in another, and that would be it. The question of whether they were necessary simpliciter would be like the question of whether the Parallel Postulate is true simpliciter – understood as a pure mathematical conjecture, rather than as a hypothesis about physical spacetime. In a sense, the latter question has no objective answer. In this article, I argue that paradigmatic questions of modal metaphysics are like the Parallel Postulate question. I then discuss the deflationary ramifications of this argument. I conclude with an alternative conception of the space of possibility. According to this conception, there is no objective boundary between possibility and impossibility. Along the way, I sketch an analogy between modal metaphysics and set theory.
