"Whatever we postulate as a beginning of pure science must be, as such, not yet scientifically determined. It is the object of pure science to develop a system, and of course the beginning cannot be a system. Since in pure science we must not receive determinations (attributes, qualities, categories, definitions, logical terms, &c.) except those justified and defined by the system, any determination that we postulate, and that is not objectively evolved, must be regarded as unscientific and therefore rejected. Determination and negation are identical, and the complete removal of determination or negation should give us pure being as a beginning or starting-point of our system. Were our system to start with any other category, as for example with the Ego, that category must be as empty as pare being; if not, it would contain pure being plus determinations, and thus duality would be present before the system had evolved it. It would be ostensibly seized as a simple somewhat, and yet the mind would mean something else more concrete. Science has to do with what is expressed and not with what is merely meant. Hence, unless Science is to start unscientifically, it must commence with pure Being."
