Discussion Overview

The discussion revolves around the minimal conditions necessary for life, inspired by Schrödinger's "What is Life?" and further informed by advancements in molecular genetics. Participants explore various aspects of life, including the essential elements for living organisms, the nature of viruses, and the potential for life to arise from nanotechnology. The conversation also touches on the concept of consciousness and the possibility of silicon-based life.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants question whether carbon is an essential atom for life and discuss the individuality of systems with membranes.
  • There is debate over whether viruses should be classified as living forms or merely as transposons or prions.
  • One participant proposes the idea of life formation through nanotechnology.
  • Frank J. Tipler's definition of life as information preserved by natural selection is critiqued, with concerns raised about its implications, such as the classification of automobiles as alive.
  • Participants express interest in the concept of silicon-based life and its potential equivalence to carbon-based life, particularly in relation to consciousness.
  • There is a discussion about the nature of consciousness, with some asserting that consciousness is present in simple organisms like amoebas, while others suggest it could also apply to artificial entities.
  • Details about extremophiles are shared, including their growth conditions and the extreme environments they can survive in.

Areas of Agreement / Disagreement

Participants express a range of views on the definitions and conditions of life, with no consensus reached. The discussion includes competing perspectives on the nature of consciousness and the classification of various entities as living or non-living.

Contextual Notes

Some claims about consciousness and the definitions of life depend on specific interpretations and assumptions that are not universally agreed upon. The discussion includes unresolved questions about the implications of definitions and the nature of life itself.

Another Asilomar?

Manipulation of biological systems seems today too easy, and it involves serious risks, besides obvious potentials to Medicine and Basic Science.
In 1975, a similar worry arose from the new DNA recombinant technologies. But now, the potential to change living forms is greater and could be amplified by the potential to access to databases of virulent microbial genetic sequences through Internet. Besides a risk of bioterrorism, there is a potential of serious hazardous side effects.
