This is a paper about two philosophers who wrote to each other. One is famous; the other is not. It is about two practical standpoints, the strategic and the human, and what the famous philosopher said of them. And it is about friendship and deception, duty and despair. That is enough by way of preamble.

Abstract: This article addresses a foundational issue in Kant's moral philosophy, the question of the relation of the Categorical Imperative to value. There is an important movement in current Kant scholarship that argues that there is a value underlying the Categorical Imperative. However, some scholars have raised doubts as to whether Kant has a conception of value that could ground the Categorical Imperative. In this paper I seek to add to these doubts by arguing, first, that value would have to (...) be of a particular kind in order to be the foundation of Kant's moral philosophy. Second, I argue that Kant does not have such a conception of value, and that his arguments rule out that value could ground his moral philosophy. I then outline an alternative reading of how Kant uses ‘inner value’. My conclusion will be that Kant does not derive the Categorical Imperative from an underlying value. While some of his passages could also be read as if value were foundational for Kant, a close look at these passages and his arguments point away from this conclusion. (shrink)

The most prominent recent interpretations of Kantian ethics place rational nature at the centre of the theory: I must respect rational nature, whether in myself or in others, because rational nature has a special status as the source of all other values. It is not obvious what it is for something to be the source of value, nor whether rational nature could play this role, but until these issues are settled the coherence of Kantian ethics is in question. In this (...) article I offer an explanation of what it is for rational nature to be the source of value, I show that this claim is an important element of Kant's moral theory, and I defend this conception of value.

This is a survey article in which I explore some important recent work on the topic in question, Kant’s formula of the end in itself (or “formula of humanity”). I first provide an overview of the formulation, including what the formula seems roughly to be saying, and what Kant’s main argument for it seems to be. I then call the reader’s attention to a variety of questions one might have about the import of and argument for this formula, alluding to (...) some of the works in which philosophers have recently raised or tried to answer these questions. Then, for the bulk of the paper, I focus my discussion on two issues of contention: the identity of the “end in itself” that the formula refers to, and the relation between the value of the end in itself and the value of other ends. I do not attempt to argue for a particular position of my own regarding these issues. Instead, I explain a number of the more interesting or influential recent attempts to answer these questions, compare these approaches in various ways, draw implications from them, and raise concerns about some of them. I also suggest that an important link connects the question about the identity of the end in itself and the question about the relation between the value of the end in itself in relation to the value of other ends: How one answers these questions commits one to a position on the thorny issue of whether, how, and how fully, autonomy is manifested through empirical (not simply pure) practical reason.
