Thinking and Logic is Inescapable
Imagine that I am one of the first apes to think. What happens when I see a plant? From here, the primal action is simply being aware of its existence. But the moment I became aware, almost instantly, I have also formed a concept. My mind through my brain has interpreted what my eyes saw as a separate form. And also almost instantly after being aware of the form, I am called to think of this thing as a separate entity in need of an identity. Almost instantly I need a tool to help me make this happen: a concept.
At this time, the almost automatic process comes to a halt. It is sufficient that I'm aware and that I have created a form and an identity in my mind. But this process leaps into another level when I need to communicate my experience, that is: my conscious seeing of a form. I need now to try to transmit my concept to another person the best way I could. At this level, I need to use the tools nature gave me, my mouth and my voice. I create sounds that signify my concept.
Now my friend living in the same place has seen the flower and because he too is beginning to evolve, he is capable of having a similar experience. Note, similar, not the same. Because he has different eyes, different brain, and different mind, he has a different but similar experience to me. Our experiences are not one and the same. They are unique to us. And yet they are similar because we looked at the same entity present in the physical space around us.
He has his own faculties and he can create his own unique mix of vocal sounds to signify the concept of the flower in his mind. But if he has his own mix and I have my own mix we wont know what each other is referring to. We have similar concepts but we can't communicate because we are using different words. We misunderstand each other.
Now it is for our benefit that we are able to communicate what we mean so we will have to agree to use a single mix of vocal sounds to refer to this form we saw in our place. We agreed to use flower.
