To live is to know

I do agree that to live is to know. To believe that cognition is exclusive to systems with a brain seems like a limited perception. Afer all, if cognition involves the bringing forth of a world, aren't we just making judgements on the way things are, based on our own fabricated little world? In that case, there can be no absolute way that things are, because perceptions are always varied. Nonetheless we humans can sometimes tend to think that there is indeed an absolute way and usually it is a very human-centric perspective. If all living systems are a product of nature then it makes sense that they would be connected to their environment and if everything is in a constant state of change, then wouldn't it take cognizance to know how to adapt and evolve according to the varied conditions it experiences?
