 Positions on which properties are represented in experience can be located on a rough continuum, with low-level properties (where these include color, shape, illumination, and depth) at one end, and high-level properties (where these include kind properties, agential or other emotional properties, and semantic properties) at the other. The issue is which of these properties can be perceived as being instantiated: e.g., whether one can have a visual experience that represents that someone is trying to do something. The debate about this is closely related to the earlier debate in the philosophy of science about whether one can distinguish between observational and theoretical properties (see Introduction to Suppe (1979)). In the philosophy of mind, defenders of the view that only low-level properties are represented in experience include Tye 1995, Dretske 1995, Clark 2000, Price 2009, Brogaard 2013, Bryne 2017; defenders of the view that high-level properties are represented in experience include Peacocke 1992, Siewert 1998, Bayne 2009, Masrour 2011, Nanay 2011, Block 2014, Siegel 2006 and 2017). It is worth noting that analogous debates can be pursued for views of experience that deny that experiences have accuracy conditions: for instance, if (with naive realism of the sort championed by Martin) one thinks that veridical experiences consist in being perceptually presented with an object and its properties, the debate will concern which properties of objects one can be perceptually presented with; if one is a pure sense-datum theorist, the debate will concern which properties sense-data can have.
