What is "life"? How do we define the concept?
Wed Mar 8, 2017 7:15am

It used to be that we defined (albeit in a simplified manner for the sake of discussion) life as engaging in metabolic activities.

Certainly under that definition a rock, or an electron do NOT meet the requirements to be called "alive"...

Now, if we want to redefine "life" to say anything that has "experiences" whether or not it knows it or not, then anything at all that interacts with the physical world is "alive"

After all, a rock "experiences" being eroded by rain and wind, and may even "experience" a landslide or being born by being extruded from a volcano.

But I guess that kind of makes the word "life" pretty much meaningless.

But whatever makes the writer feel good.
