Context

“As, therefore, human discrimination is to that of the lower animals, so the discrimination of the lower animals and plants is to that of inorganic things. In each case it is greater discriminating power (and this is mental power) that underlies the differentiation, but in no case can there be a denial of mental power altogether. Opinion and Matter Moral force and material force do pass into one another; a conflict of opinion often ends in a fight. Putting it the other way, there is no material conflict without attendant clash of opinion. Opinion and matter act and react as do all things else; they come up hand in hand out of something which is both and neither, but, so far as we can catch sight of either first on our mental horizon, it is opinion that is the prior of the two.” source
