What of the photosensitive ‘eyespot’ of Euglena? It’s a single-celled organism: no brain, no nerves, no “mental habits”. It just senses light, and moves towards it, the better to photosynthesise. Are you claiming that a Euglena knows what it’s doing? How about the ‘perception of a stimulus’ that causes a sea anemone’s cnida to fire? <a href="http://tolweb.org/tree?group=Cnidaria&contgroup=Animals#TOC2" target="_blank">http://tolweb.org/tree?group=Cnidaria&contgroup=Animals#TOC2</a> I don’t see any “mental habits, memory, imagination, feeling, and a will to be attentive” in this. Do you? How about various plant growth tropisms? How do they ‘know’ to grow towards light and away from gravity? How about reflexes? Hormonal responses? How about a Geiger-Muller tube, an electronic thermometer or the solar cells of a calculator? Brains are part of the nervous system, and nervous systems are not necessary to receive and act on stimulus inputs: an organism does not need to ‘perceive’, in our human sense, in order to sense things. Sure, in more ‘advanced’ animals, the CNS is used to co-ordinate all this stuff. But the basis is, noting that the environment is not homogeneous, and acting upon it. Where’s the ‘mind’ in this? Edited to add: Oh yeah, and this sensing is the result of well-understood chemistry and physics, not because there is a mind at work in it. Need I introduce you to the concept of Ockham's razor??

1. what has it to do with evolutionary theory, and how is it a problem for it? 2. whence this complexity? All the (naturally-occuring) organised complexity we know of is the result of evolution. How did this not-natural not-supernatural complexity arise? 3. please offer evidence that this complexity even exists outside of biological entities! TTFN, Oolon |

The theory of evolution you refer to, by the way... do you mean the fact of common descent, or the various scientific theories that account for it? Which theories do you consider incorrect -- natural selection, genetic drift, punctuated equilibrium...? Quote:

me: Sorry, it was Cheap Thrill who referenced Bertrand Russell. Btw, thanks for your patience in regard to this thread. I appreciate your attempt to keep me on task. Oolon: 1. what has it to do with evolutionary theory, and how is it a problem for it? me: You assert that TOE explains biological complexity and that mind being a complex thing is then explained by TOE. I agree that TOE is an EXPLANATION for complexity. However, an explanation, no matter how practical is not necessarily the correct one. I don't have to remind you that the Ptolemaic explanation of our solar system reigned for almost two thousand years as a practical explanation. It was overthrown, but only with the utmost difficulty. You would say then that all your concepts are empirical and testable. I would counter that you and modern science, by assuming physical monism, have taken the wrong road. So,while the evidence you see out your car window is explanatory of where you are going; eventually, you will have to turn around and head back when the signs of a dead end can no longer be dismissed as irrelevant. The only way I can do this is by arguing, philosophically, the errant causality which as plagued the modern scientific paradigm. That, as I suggested in a much earlier post and Cheap Thrill and you have pointed out, should be attempted on the philosophy forum. And that is what I will do. The alternative to the TOE, as an explanation of complexity, is the theory of an "Evolution of Conciousness" which Owen Barfield in his book 'Saving the Appearances' outlines very clearly. When the theory is adaquately explained I believe it will be seen to satisfy the requirements of Occam's razor quite well. Thanks for your time and comments. I will pack my bags and move to the afore-mentioned forum. |

you said: What sort of ‘meaning’ do you think life should have then? And how is it something empirical, rather than something we ourselves construct? me: Empirical data requires scientific man to become more and more an onlooker, measuring with greater and greater precision, manipulating more and more cleverly an earth with which he "spiritually" becomes more and more a stranger. So, he can describe, weigh, and measure the processes of nature and to a large extent to control them; but the price he has paid has been the loss of his grasp of any meaning in either nature or himself as you imply in your above post. Penetration to the meaning of a thing or process, as distinct from the ability to describe it exactly, involves a participation by the knower in the known. The meaning of what I am typing on the keyboard is not the physical pressure of fingers on the keys. Rather, it is the concepts expressed by the words I am typing. The only way of penetrating to these is to participate in them-to bring them to life in one's own mind by thinking them. A Russian, not knowing the English language, looking at this post would indeed be limited to describing its outer appearance. We are mere onlookers at a language we do not understand. But confronted with a language we have learned to understand, we not merely observe the shapes of the letters-in the very act of observing these we "read" their meaning through them. In the same way, if we want to know the meaning of nature, we must learn to read as well as to observe and describe. And we only can begin to "read" the meaning of nature, when we begin to apprehend it as a series of images symbolizing concepts. A contruct of our mind. Yes! So to find meaning I suggest you must learn to "read", while retaining your hard-won treasure of exact observation and manipulative control-for no one would advocate a mere relapse into the past. |
