 While Wolff emphasizes that science is a “habit of the understanding”, this should be taken to also involve the human capacity of reason, inasmuch as it is the faculty for perceiving the connection between truths. When properly employed, then, human reason can discern groups of facts, establish a certain order and interconnectedness between these facts, and ultimately justify them as being certain parts of human knowledge. Put slightly differently, science is a disposition or ability of the human mind to conceive the facts of reality in an ordered and structured way. Individual sciences, therefore, such as theology, cosmology, or psychology, are simply the various sets, or subsets of demonstrable cognitions and the principles (including axioms, definitions, and empirical facts) from which they are derived.
