I mean for the category to include the use of \u00a0telescopes, hearing aids, sensory substitution devices, and also fuel and other gauges,\u00a0perhaps even psychedelic drugs and virtual or augmented reality. I presume that prosthetic perception can give us knowledge and justified belief\u2014indeed, this is part of what distinguishes them from \u201csensory engineering\u201d more generally. Here I want to explore questions of how this knowledge is like or unlike the knowledge associated with ordinary perception. In particular, I\u2019m interested in two questions about the directness of prosthetic perception: (a) does it provide new knowledge\/justification by allowing us to <em>perceive<\/em> (literally see\/hear\/etc.) things (objects\/properties\/events\/etc.) that we couldn\u2019t otherwise? And (b) is prosthetic perception inferential in a way that ordinary perception is not? I will also be asking whether and how these two questions are related, as the answer to the second might well be constrained by the answer to the first. My discussion will be framed in terms of Dretske\u2019s seminal (1969) discussion of nonepistemic, primary epistemic, and secondary epistemic seeing, but also in terms of inferentialism and presumptivism from the recent testimony debate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Knowing from Prosthetic Perception Jack Lyons University of Glasgow &nbsp; Prosthetic perception is perception that is enabled or facilitated by a mechanism designed to generate a type or quality of&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","meta":{"_tribe_events_status":"","_tribe_events_status_reason":"","_tribe_events_is_hybrid":"","_tribe_events_is_virtual":"","_tribe_events_virtual_video_source":"","_tribe_events_virtual_embed_video":"","_tribe_events_virtual_linked_button_text":"","_tribe_events_virtual_linked_button":"","_tribe_events_virtual_show_embed_at":"","_tribe_events_virtual_show_embed_to":[],"_tribe_events_virtual_show_on_event":"","_tribe_events_virtual_show_on_views":"","_tribe_events_virtual_url":"","footnotes":""},"tags":[],"tribe_events_cat":[5],"class_list":["post-15752","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-epistemology-seminar","cat_epistemology-seminar"],"_links":{"self":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events\/15752","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":2,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events\/15752\/revisions"}],"predecessor-version":[{"id":16042,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events\/15752\/revisions\/16042"}],"wp:attachment":[{"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/media?parent=15752"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tags?post=15752"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/www.st-andrews.ac.uk\/philevents\/wp-json\/wp\/v2\/tribe_events_cat?post=15752"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
