MaxCathedral Posted May 25, 2004 Share Posted May 25, 2004 What is life? Is it that which reproduces? That which converts energy? That which moves. Why is a tree life, but a rock not? Dying to hear the different definitions. Max Link to comment Share on other sites More sharing options...

YT2095 Posted May 29, 2004 Share Posted May 29, 2004 no no no, I`m fairly sure it`s closer to something like: Movement Respiration Sensitivity Nutrients (requiring) Excretion Reproduction and Growth as you can see it clearly has 7 elements Link to comment Share on other sites More sharing options...

Glider Posted May 30, 2004 Share Posted May 30, 2004 Cognition is difficult in single celled life like algae, dontcha think? Link to comment Share on other sites More sharing options...
admiral_ju00 Posted May 30, 2004 Share Posted May 30, 2004 Cognition is difficult in single celled life like algae, dontcha think? only if limiting the term to humanity. like Maturana said, a baterium while does not have cognition as you and i know it, but it can sense if there's acid nearby and swim away from or food and swim to, etc. basically, the idea is to think outside the box. here's a brief excerpt http://www.geocities.com/combusem/CAPRA4.HTM Link to comment Share on other sites More sharing options...
YT2095 Posted May 30, 2004 Share Posted May 30, 2004 also Cognition as specifyed by the Santiago Theory well even if we did accept cognitive behaviour (and I don`t) that would make it 8 points, and certainly not 5 as stated Link to comment Share on other sites More sharing options...

To use the term 'cognition' to explain the heliotropic properties of a plant would be inappropriate. There is a difference between 'sensitivity' to something and 'sensing' it.

admiral_ju00 Posted May 31, 2004 Share Posted May 31, 2004 yep, i know. but i didn't say you got to buy what's in the Santiago theory, i merely threw it down on the table Link to comment Share on other sites More sharing options...
Crash Posted May 31, 2004 Share Posted May 31, 2004 I think life from a scientific point of view is the opposite of death, so deifne death ivert it and budda bing you have the meaning of life Link to comment Share on other sites More sharing options...
Duke Posted May 31, 2004 Share Posted May 31, 2004 Thats more of a philosophical way of thinking. Fair enough the opposite of death is life but you have to be able to define life before hand to understand what death isn't. Link to comment Share on other sites More sharing options...
Crash Posted May 31, 2004 Share Posted May 31, 2004 Actually i thought death was easier to define than life....as for the philosophical version death is heaven/hell....etc I see death as the cease of all response from an organism or the loss of the MRSGREN points YT had gonna go get a dictionary Link to comment Share on other sites More sharing options...
