And the intuitive reason [the last of the four faculties above enumerated] also deals with ultimate truths, in both senses of the word; 160 for both primary principles and ultimate facts [in the narrower sense of the word ultimate = particular] are apprehended by the intuitive reason, and not by demonstration: on the one hand, in connection with deductions [of general truths in morals and politics], 161 reason apprehends the unalterable first principles; on the other hand, in connection with practical calculations, reason apprehends the ultimate [particular] alterable fact which forms the minor premise [in the practical syllogism]. These particular judgments, we may say, are given by reason, as they are the source of our conception of the final cause or end of man; the universal principle is elicited from the particular facts: these particular facts, therefore, must be apprehended by a sense or intuitive perception; and this is reason. 162
