Christopher Peacocke, Mountains and Mountaineering

On page 67 of his A Study of Concepts (MIT Press, 1992), Peacocke offers the 'fine-grained of experience argument' in favour of non-conceptual content, saying: "If you are looking at a range of mountains, it may be correct to say that you see some as rounded, some as rugged. But the content of your visual experience in respect of the shape of the mountains is far more specific than that description indicates."
