They believe not only that the soul has the capabilities I mentioned above, but that it can function independently of the body (after death, for example).\u00a0 That commits them to substance dualism, which is very hard to reconcile with the split-brain observations.<\/p>\n<p>Vincent, for you the soul seems to be inseparable from the body.\u00a0 For example, you write<\/p>\n<blockquote><p>&#8230;mind and body (or rather, soul and body) are <i>not<\/i> two things; rather, the human person is an essential unity.<\/p><\/blockquote>\n<p>You also write:<\/p>\n<blockquote><p>It should be noted that <i>memory<\/i> is viewed as a bodily capacity on both versions of dualism being discussed here. Neither account envisages us as having an \u201cinvisible information bank\u201d in an immaterial soul, where we keep our memories. Memories, on both accounts, are stored in the brain.<\/p><\/blockquote>\n<p>Those quotes seem to indicate that you, unlike most of your fellow theists, do <em>not<\/em>\u00a0think that the soul can function independently of the body.\u00a0 Is that true?\u00a0 Don&#8217;t you think the soul lives on after death? If so, does it lose its memories?<\/p>\n<p>I\u2019ll have much more to say in the comments, but I think this is an appropriate stopping point until you have given us a better understanding of your exact position.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The immaterial soul, at least as most theists conceive of it, does not exist.\u00a0 There is an abundance of evidence for this assertion, but I have focused recently (both here and at UD) on observations of split-brain patients in particular. &hellip; <a href=\"http:\/\/theskepticalzone.com\/wp\/more-on-split-brains-and-souls\/\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":20,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2888","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/posts\/2888","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/comments?post=2888"}],"version-history":[{"count":0,"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/posts\/2888\/revisions"}],"wp:attachment":[{"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/media?parent=2888"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/categories?post=2888"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/theskepticalzone.com\/wp\/wp-json\/wp\/v2\/tags?post=2888"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
