This paper concerns what I take to be the primary epistemological motivation for defending moral perception. Offering a plausible account of how we gain moral knowledge is one of the central challenges of metaethics. It seems moral perception might help us meet this challenge. The possibility that we know about the instantiation of moral properties in something like the way we know that there is a bus passing in front of us raises the alluring prospect of subsuming moral epistemology under (...) the comfortable umbrella of perceptual or, more broadly, empirical knowledge. The good news on this front is that various combinations of metaethical positions and theories of perception arguably have the potential to vindicate moral perception. The bad news, I’ll argue, is that moral perception would be dependent for its epistemic merit on background knowledge of bridge principles linking moral and non-moral properties. Thus, in order to defend a purely perceptual moral epistemology, one would have to argue that knowledge of those principles is likewise perceptual. I further argue it is not. (shrink)

According to contentful moral perception (CMP), moral properties can be perceived in the same sense as tables, tigers, and tomatoes. Recently, Heather Logue (2012) has distinguished between two potential ways of perceiving a property. A Kantian Property (KP) in perception is one in which a perceiver’s access involves a detection of the property via a representational vehicle. A Berkeleyan Property (BP) in perception is one in which a perceiver’s access to the property involves that property as partly constitutive of the (...) experience itself. In this paper, I set aside generalized arguments in favor of one view or another, and instead ask whether proponents of CMP have reasons to understand moral perception as Kantian or Berkeleyan. I explore three possible explanatory differences—(a) explaining the intrinsic motivating force of moral perceptions, (b) providing a metasemantics for moral properties, and (c) providing an epistemology of the normative authority of moral properties.

One of the arguments that is put forward both for and against strong moral realism is the argument for the causal effects of moral properties; Whether moral properties have a causal effect on the external and physical world to prove their reality or not. The first who argue this was Gilbert Harman, who considered moral properties to have no causal effects. Shafer-Landau has also obtained an ontological account of it and examined it. In this article, we examine the arguments of (...) Harman and Landau and the drawbacks that have been made to them, and the result is that the arguments of those who consider moral properties to have no causal effects have significant drawbacks and are not defensible. Explanations can also be used to defend the causal effects of moral properties and to use them to the benefit of realism. (shrink)
