It is certainly true that living beings have organic integrity and self-directed (aka immanent) activity. So, as a result of their form, organisms act in a way that non-living matter does not. Still, this activity is potential in non-living matter. So, mechanists are correct in saying that the same laws guiding non-living matter guide the behavior of living matter. Still, those laws do not provide a full explanation. They allow, but do not imply life. To have life, we need to specify forms of matter that can live. It is those forms, as Aristotle saw, that make the difference between living and non-living matter. — Dfpolis
Thank you for your comments, and pleased to have found some common ground. Many of the contemporary theorists I'm reading refer to this aspect of Aristotle's philosophy (his Biology is, I think, considered relevant in ways that his Physics is not. Some say he anticipated the idea of DNA, though obviously not the molecular detail.)
So, we can only say that non-conscious forms of life "interpret" or "value" only by anthropomorphizing, and doing so abuses language by stripping interpretation and valuing of their essential, conscious and intentional character. — Dfpolis
Here, however, is where I would draw attention to the emerging school of thought known as 'enactivism' or 'embodied cognition'. This school of thought enlarges the meaning of intent (or value or purpose) beyond that which only conscious subjects are able to entertain. There's quite a large literature on the subject, and it is difficult to summarise, so I've asked Google Gemini to
create a primer for it, which explains some of the key concepts and texts. Strictly speaking, the main subject of its enquiries are cognition, rather than consciousness
per se, however, as you can surmise, there is considerable overlap in these terms. So it is not a matter of 'abusing language' - the terms are being used in a broader way, and in a new context.
As a corrollary to this, I think the theorists in these schools would question whether organisms at any level of development act solely in accordance with the principles of physics and chemistry. As has been pointed out by the mainstream biologist Ernst Mayer 'The discovery of the genetic code was a breakthrough of the first order. It showed why organisms are fundamentally different from any kind of nonliving material. There is nothing in the inanimate world that has a genetic program which stores information.' Even simple organisms strive, persist, and preserve themselves which has been illustrated in the activities of the slime mould, which is a single-celled organism with no identifiable brain whatever (for which see
How the Universe Thinks without a Brain).
Yes, but that does not make them subjects in the sense humans are. — Dfpolis
No contest! But, again I am working with a rather broader concept of subject-hood than conscious subjectiivity. (The term for the sense of 'being a subject' is 'ipseity' which is being extended somewhat through these new disciplines to encompass the awareness of organisms less developed than the higher animals.)
I fully acknowledge that this way of thinking is new to me, I still have much more to study and absorb, and I may therefore be mistaken in my presentation of these ideas. But I think to make that judgement some familiarity with the key texts and concepts is required.
Deterministic genetic variation and mutation produce variant offspring that are selected by processes guided by the same laws of nature. — Dfpolis
As I understand it, a better understanding of epigenetics undermines the idea that genetic variation is purely deterministic. Variation can be systemic, responsive, and developmentally mediated, not just molecular noise filtered by selection. Organisms are not just passive recipients of selective pressures — they are
active participants in shaping their own evolutionary and developmental environments.
Questions of the meaning of life long predate the scientific revolution, so it is suspect to make it somehow responsible for a fundamental human question such as this. — hypericin
On the contrary, the idea that the Universe can be understood in terms of undirected physical interactions and processes is very specific to post-scientific revolution. And I question that pre-moderns would typically wonder about ‘the meaning of it all’, as existence in those times was very much circumscribed by custom and your place in the social hierarchy (not that this was necessarily a good thing.)
The real ‘crisis of meaning’ is very much associated with the advent of modern technological and (post) industrial culture. And again the absence of meaningful social structures is not necessarily negative, as individuals are much more at liberty to pursue their own ends. But it can’t be denied that feelings of alienation, disconnectedness, loneliness and anomie are characteristic of modern culture and that this is often underwritten by a sense of meaninglessness.
What your essay seems to miss is the notion of hierarchy in purpose. Of course, biological life is full of purpose, at every scale. But at every point where purpose is found, one can ask what purpose does that serve? — hypericin
I didn’t say nor imply that there isn’t a hierarchy of meanings. At the most basic level the organism’s purpose, and the overall aim at which all of its constituent parts are engaged with, is persisting, staying alive. This drive animates (literally) all living creatures.
