First correlate

Represented by 1C. It corresponds to the presentative character of the sign, or the manner as it presents itself to an interpreter, regardless of the object that it professes to represent or the effect that it produces. It is the sign itself (S), whose signic capacity is due to its ground – the universe of possibilities of representation that, when an occasion occurs, will enable it to be taken as a sign of its object. Due to the rule of material implication among the correlates, the First Correlate is the one that determines the others, which can only be Thirdness if the First Correlate is too.
