 Kantian constructivism inverts the relationship realists see between objectivity and truth; rather than objective judgments being grounded in the discernment of antecedent objects of truth, objectivity (of judgment) precedes the object (of truth). This means that at the level of fundamental moral principles the correctness of these principles depends, not on their correspondence to a prior moral order, but on their following from (or being among) the fundamental principles of practical reasoning. The objectivity of judgment that is involved in reasoning from an objective perspective according to relevant principles of practical reasoning results in objective moral principles that are the bases for judgments of moral truth. The moral facts that are the objects of these moral truths are not then prior to, but are the facts that are singled out as relevant by moral principles and principles of practical reasoning (CP 516).
