If we understand this, we unravel humanity, in fact pretty much all beings – everything that exists is a composite of three things: a. it has a brain – b. it has feelings – now the brain serves the feelings, and only in humans, whose brain can be separate from the feelings (we are the only beings that have a prefrontal lobe) can it also work in the reverse (namely the brain can create feelings) and the feelings create expression (such as thoughts, speech or action – obviously at the very core must be the will to exist and its flipside, the fear of not)
