Third, and related to the previous: I don’t think the issue about consciousness is fundamentally about qualities at all. That is, a moment’s reflection should make it clear that physical properties, quantities etc. are qualities too. The problem with consciousness is about something else. What?
14.02.2026 18:58 — 👍 0 🔁 0 💬 2 📌 0Second, the quality/quantity distinction is problematic. Is mathematics either? Which? Most importantly: the two are not mutually exclusive, and it’s clear that there’s a lot of mathematics about qualities.
14.02.2026 18:57 — 👍 0 🔁 0 💬 1 📌 0First, mathematics = abstract, but physical = concrete. That’s why “mathematical physics” has been a problematic notion (downright an oxymoron) from the get-go (for physicists/philosophers of nature). There’s many who would say that mathematics belongs to the mental realm.
14.02.2026 18:56 — 👍 0 🔁 0 💬 1 📌 0It’s of course not at all clear what “physicalism” is supposed to amount to. You jump to speaking in terms of “mathematical physics”. This is fine, but I’m not totally sure that the physicalism vs mental issue in philosophy is an issue about mathematical physics vs mental. A number of things here:
14.02.2026 18:55 — 👍 0 🔁 0 💬 1 📌 0Your answer to my first question leads into much more interesting waters. I don’t know Galileo’s stuff as well as I should – maybe you know “a book” that gives a nice rundown of the things you mention? (If I dare to ask.)
14.02.2026 18:54 — 👍 0 🔁 0 💬 1 📌 0From these I conclude that *if there’s ever going to be some satisfactory explanation of consciousness (i.e. first person experiences), it’ll be in terms of physicalism. That’s what my tweet above was about: if I’d need to bet, it’d bet on physicalism.
14.02.2026 18:54 — 👍 1 🔁 0 💬 1 📌 0Second, I’m fine with leaving that stuff without explanation, and I’m not even sure what/how we are supposed give an explanation here – and how e.g. panpsychism could provide such.
14.02.2026 18:53 — 👍 0 🔁 0 💬 1 📌 0Two points. First, there’s much more to explain than first person experiences – even when we confine ourselves to psychology. And physicalism has done pretty damn well in many cases.
14.02.2026 18:52 — 👍 0 🔁 0 💬 1 📌 1Alrighty. Bunch of things here. Let’s start with the easy one, the second question. You say:
“we haven't managed to explain how physical processes could produce first person experience”
I agree with this. Most people in science/philosophy do. But it’s wrong to bin physicalism because of this.
En tiedä, missä ryhmävalintakeskustelu menee yleisemminkään nykyään (siis biologiassa). Odottelen tässä opiskelijaesseetä aiheesta; toivottavasti sivistyn. Mutta peruspointsi se, että sukulaisvalinta ja resiprokismi ovat fundamentaalisti eri selityksiä (jälkimmäinen ei edellytä sukulaisuussuhdetta).

Noh, itse käsitän resiprookkisuuden "fitness interdependence" -ilmiöksi. Historiallisestihan tässä on se tausta, että ryhmävalintaa (minkälaiseen terminologiaan pop-keskustelussa edelleen törmää) pidettiin epäpätevänä. Sukulaistavalinta & resiprookkisuus selittävät altruismin yksilö/geenivalinnalla.
14.02.2026 14:43 — 👍 0 🔁 0 💬 1 📌 0En itse niin tätä psykologista keskustelua tunne. Mutta esim. hoivan biologinen perusta on helppo ymmärtää. Ihmisten kohdalla puhumme kuitenkin yleensä altruismityypistä, joka ei selity sukulaisvalinnalla, vaan resiprookkisuudella. Selkeyttää keskustelua, kun tämä ero on kirkkaana mielessä.
14.02.2026 12:27 — 👍 1 🔁 0 💬 1 📌 0Tässä pitää olla tarkkana. Sukulaisvalinnan teorialla on hyvin vähän tekemistä psykologian/kulttuurin kanssa ("itsekäs geeni" tietty huono termi). Teoria selittää, miksi on lisääntymiskyvyttömiä eliöitä yms. Resiprookkinen altruismi on sitten toinen juttu (josta on myös solidia teoriaa/evidenssiä).

Onko näyttöön perustuva psykiatria mahdollista?
Erityisesti tutkijan kevätkouluun kutsutaan mukaan osallistujia.
Tavoitteena on monitieteinen tilaisuus.
Two questions:
(1) How, exactly, did Galileo take consciousness outside of "the scientific domain of science"? (An off-hand reference to a book won't qualify as an answer.)
(2) Physicalism has never been cashed?
I think Marie Curie is still the only person who has been awarded two Nobel Prizes in two separate sciences.
