§ 43. The origin of the transcendental Ideas is the three forms of syllogism that reason uses in its activity. The first Idea is based on the categorical syllogism. It is the psychological Idea of the complete substantial subject. This Idea results in a paralogism, or unwittingly false dialectical reasoning. The second Idea is based on the hypothetical syllogism. It is the cosmological Idea of the complete series of conditions. This Idea results in an antinomy, or contradiction. The third Idea is based on the disjunctive syllogism. It is the theological Idea of the complete complex of everything that is possible. This Idea results in the dialectical problem of the Ideal. In this way, reason and its claims are completely and systematically considered.
