Negativity, the name given in philosophy to the negative element determinative or definitive of things and all ideas of things, whereby a thing is this because it is not that, and is seen to be this because it is seen not to be that, an antagonism essential to all forms of being, spiritual as well as material, and to all definite and distinct thought.
Definition taken from The Nuttall Encyclopædia, edited by the Reverend James Wood (1907)
