I am struggling with your use of the word closure, but I think you have it as I would have it. Philosophers (at a wild guess) seem to identify intensions with the ineffable mental states that (known only to the actor) guide the actors actions, or, even more narrowly, with the entailments of statements including verbs of mentation. I think intensionality is everywhere in the world around us. Every control system embodies intensionality. Your thermostat is an intensional device. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks for hanging in with me on this. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nick <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Nicholas Thompson<o:p></o:p></p><p class=MsoNormal>Emeritus Professor of Ethology and Psychology<o:p></o:p></p><p class=MsoNormal>Clark University<o:p></o:p></p><p class=MsoNormal><a href="mailto:ThompNickSon2@gmail.com">ThompNickSon2@gmail.com</a><o:p></o:p></p><p class=MsoNormal><a href="https://wordpress.clarku.edu/nthompson/">https://wordpress.clarku.edu/nthompson/</a><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> Friam <friam-bounces@redfish.com> <b>On Behalf Of </b>Jon Zingale<br><b>Sent:</b> Saturday, May 16, 2020 11:16 AM<br><b>To:</b> friam@redfish.com<br><b>Subject:</b> Re: [FRIAM] intension/extension<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-family:"Times New Roman",serif;color:#1A1A1A'>Nick,</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-family:"Garamond",serif;color:#1A1A1A'>From the Stanford Encyclopedia article:</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='font-family:"Times New Roman",serif;color:#1A1A1A'>"Although the meaning of the word \u2018intentionality\u2019 in contemporary philosophy is related to the meanings of such words as \u2018intension\u2019 (or \u2018intensionality\u2019 with an <em>s</em>) and \u2018intention,\u2019 nonetheless it ought not to be confused with either of them. On the one hand, in contemporary English, \u2018intensional\u2019 and \u2018intensionality\u2019 mean \u2018non-extensional\u2019 and \u2018non-extensionality,\u2019 where both extensionality and intensionality are logical features of words and sentences. For example, \u2018creature with a heart\u2019 and \u2018creature with a kidney\u2019 have the same extension because they are true of the same individuals: all the creatures with a kidney are creatures with a heart. But the two expressions have different intensions because the word \u2018heart\u2019 does not have the same extension, let alone the same meaning, as the word \u2018kidney.\u2019 On the other hand, intention and intending are specific states of mind that, unlike beliefs, judgments, hopes, desires or fears, play a distinctive role in the etiology of actions. By contrast, intentionality is a pervasive feature of many different mental states: beliefs, hopes, judgments, intentions, love and hatred all exhibit intentionality. In fact, Brentano held that intentionality is the hallmark of the mental: much of twentieth century philosophy of mind has been shaped by what, in this entry, will be referred to as \u201cBrentano\u2019s third thesis.\u201d"</span><span style='font-family:"Garamond",serif;color:#333333'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Garamond",serif;color:#333333'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Times New Roman",serif;color:#1A1A1A'>One point you made in chat that I found interesting is the</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='font-family:"Times New Roman",serif;color:#1A1A1A'>possible intersection of the two concepts.
