Plants are not conscious, but they still go on stretching up to the sky and scattering seeds.
Worms probably aren`t aware of the pleasing squelch of mud, but they go on burrowing through it.
Human are conscious.We are conscious of seeing things, learning things, reaching out to touch things, deliberating ethical questions, making decisions, fancying someone and setting goals.
But consciousnessisn`t needed for any of this things.
In fact, when we do them, it generally isn`t consciousness doing them at all. Our conscious experience is separate from the process in the brain that actually decide things, guide us as wreath out of things or set our goals. This explain why so many of the ways in which psychologists can manipulate us seem strange to us: if consciousness determined our behavior we`d already know that was how we worked, but as it does not, we do not.
