It's a good example of why the old school book definition of life - respiration, reproduction, growth, etc, isn't correct.Well I'm sure you would agree that fire meets some of the criteria for life, even if it's nonlife.
(Systema Naturæ)NATURALIA sunt corpora cuncta Creatoris manu composita, Tellurem constituentia, In Regna Naturæ tria divisa, quorum limites concurrunt in Zoophytis.
Lapides: corpora congesta, nec viva, nec sentientia.
Vegetabilia: corp. organisata & viva, non sentientia.
Animalia: Corp. organisata & viva, & sentientia, sponteque se moventia.
These are antiquated.(Systema Naturæ)
So, nature is divided into three kingdoms.
Rocks - bodies which accumulate, are not alive nor sentient.
Plants - bodies which are organized and alive, but not sentient.
Animals - bodies which are organized, sentient and which may move themselves.
You don't say? :tongue2: Maybe I should've taken a hint from Linnaeus' mention of "the four elements" on the preceding page :)These are antiquated.
Nope, they are in fact the same 'kingdoms', as it was Linnaeus who invented the whole classification system. Just in the original form. Since his classification system is the one still in use today, obviously there have been major revisions.First, a clarification: Presumably, these are not the same "kingdoms" as in the kingdoms of life, since rocks don't belong. Also, there are more than two kingdoms of life - there are about five now - critters that are neither plant nor animal.
Actually you could in principal make a new rabbit if you worked fastFire does not change its process to adapt to its environment, e.g. moving toward more fuel or storing and conserving fuel when it is in short supply. Fire does not convey information via replicating as in genetic code. It is just a raw physical reaction.
Note that "killing a fire" and reigniting it is indistinguishable from just letting it continue.
This generally will distinguish life from non-life. If you kill a rabbit you can't recreate a rabbit just from the materials at hand.
- Stephen HawkingI think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
I think fire is irritated by water, everytime I pour water on a fire it would hiss in protest...Does fire have a property of Irritability? That is, can fire react to a stimulus? A long time ago, a biological science authority listed irritability as a property of life. For Fire, irritability may not be enough by itself. Besides, fire seems limited at best in how it might react to any stimulus.
Clever, but I think he means the fire would try moving away from the water. Instead it just dies creates a a barrier from its food.I think fire is irritated by water, everytime I pour water on a fire it would hiss in protest...
