Discussion Overview

The discussion revolves around whether a robot, particularly one that is self-replicating or self-growing and programmed to make logical decisions, can be classified as a living thing. Participants explore definitions of life, the characteristics that might qualify a being as living, and the implications of mechanical versus biological existence.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants suggest that the definition of a living thing is contingent on biological versus mechanical nature, implying that most would consider living things to be biological.
  • There is a proposal that the definition of life includes characteristics such as eating, excreting, respiration, growth, reproduction, and reaction to stimuli, though some participants challenge the necessity of all these criteria.
  • A thought experiment is presented regarding the gradual replacement of human organs with mechanical substitutes, questioning at what point a person ceases to be human, which parallels the discussion of robots and life.
  • Some argue that consumption of energy and reproduction are essential criteria for life, while others contend that these concepts are too personalized and may not apply universally.
  • One participant suggests that as long as a being can consume energy and maintain its Gibbs' free energy above equilibrium, it could be considered alive, regardless of its origin.
  • There is a discussion on the vagueness of terms like "response to stimuli," with some questioning whether a being that does not respond to stimuli can be considered alive.
  • Some participants express that the complexity of defining life may lead to endless debate, suggesting that the term "living" might be fundamentally vague or meaningless.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definition of life or whether robots can be considered living things. Multiple competing views remain, particularly regarding the criteria that must be met for something to be classified as alive.

Contextual Notes

Discussions highlight limitations in definitions and assumptions about life, as well as the complexity of distinguishing between biological and mechanical entities. The conversation also reflects varying interpretations of essential life characteristics.

You're illustrating a point I made earlier that the scientific definition may change if we face a robot that our brain will obviously consider alive. I was answered that the biological definition of life is narrow and focused. And excluded viruses. :redface:

Even if you choose to consider viruses as non-living, they are RNA and DNA based replicating entities which interact with cell-based life to such an extent that no biologist would deny they are proper, in fact essential, subjects in the study of living systems.

You don't get my point. This is not my choice, but that was the choice of most biologists before the mimiviruses (I'm not sure of the present consensus). I'm just stating this an example that what we call scientific definition is obviously subject to change. Thus, when you argue that robots are not defined as living form, I'm not arguing this is not the present definition. I'm just underling that this definition may well change in the future, as it did before (at least for a couple of biologist, including me).

Who said these type of questions are only for philosophers? I didn't. I said this was a philosophical question. The scientific answer to the OP's question is "no". The biological definition of life is narrow and focused: RNA, DNA based replicating organisms including viruses. Prions are borderline, but are studied by biologists because they are replicating proteins and interact with living systems. Beyond this we get into opinions and speculation.

The ethical questions that might arise with intelligent robots certainly are important philosophical questions deserving serious discussion. Should a science forum deal with ethics (other than perhaps the ethics of practicing science)? I don't think so, but that doesn't mean scientists shouldn't get involved.

his question belongs in the philosophy forum, not biology. language follows reality, not the other way around.

Huh, that seems fairly clear cut, and beyond that I'm not going on a tangent of a tangent... this isn't GD. If you want to scuttle the thread, do it alone.

OK. But there's a difference between saying 'a virus is alive' and a virus is 'an RNA,DNA based replicating entity'. The former might be subject to change, but the latter is just a fact. I'm not saying that science forum discussions ought to only discuss facts, but they should stay within the bounds of accepted theory and conventions surrounding those facts. It probably doesn't matter that much whether you want consider viruses as alive or not as long as you accept the objective knowledge regarding viruses and their importance in biology.

The latter is only true if they have a host to follow instructions and replicate. Ever see a "brick" of amplified Ebola?... not exactly alive if you take it out of its element.

Anyway, as the beginning of this thread proposed self-replicating machines, viruses are simply not included, de facto.

Sure! But why do you think it can change?

I believe the answer to that would be skirting the definitions between alive and sentient.

To be alive, would not the subject need to be sentient as well?

If not, what is the definition of living thing?

I stand on the answer of no. the robot would not be alive. as it is not sientient. you could program it to be (to a point) self aware.

but you have me whooped on

What if in the future we can control cells that already exist and give (take from) them the genes (and regulatory DNA) we want? And construct cell networks and get them to differentiate and reproduce in our own novel way? Then start selecting for human usefulness (while still experimenting with bio-engineering)?

Everyone is a fan in theory, it's the practice that makes monsters.

we are not defining alive with "what if's".

We define everything in those terms.

I do not agree. We do not define knowledge with "what it" we define it with facts, proven and re-creatable data that is as close to irrefutable as possible.

the "what ifs" are what causes science to look for the facts to prove or disprove it.

The truth is. we need the What ifs, they help the sturdy minded, non free thinking, humans to look outside the box.

Then by all means, tell me how you prove an artificial construct for humans to demarcate something that only matters to us?

The truth may be, but we deal with theories, all of which are wrong... and that's not my original thinking there. In a science as far from physics as biology, you begin to tread the waters between science and art.

I may misunderstand your request to "prove an artificial construct for humans to demarcate something that only matters to us"

In truth I had to look Demarcate up.
if to make a construct set the boundaries we wish, that matter to us. its called programing.
I'm not trying to be a jerk. but i did not want to let a lack of response mean i was mistaken.


What I meant by the "what if" is that we are looking to define what is "alive" and not what if we use bioengineering to blah blah blah. it was opening a road to a different destination.

Ahhhh... you mean what do we treat as life, vs. what we treat as a "creation" of ours and a tool?
