  When we think in propositions, we usually think directly; direct thinking is everyday cognition such as knowing to proceed at green lights or knowing dentists' chairs are frightening. All humanity thinks directly, or in these ordinary ways, but some persons engage in reflexive thought, or about the mind itself and its contents. In reflexive thought, there is a return of the mind onto itself, or an attending to the contents of the mind; such reflexive thoughts are more attentive perceptions of the divine ideas, and these thoughts are contemplations of the eternal truths. Norris states along with Locke (Essay 4.3.2) that knowledge is perceiving “those Relations of agreement or disagreement that are between Ideas, which whoever clearly and rightly perceives, is truly said to know” (Theory II 147–148). Knowledge of the eternal truths, of course, is the highest grade of knowledge, or scientia. By engaging in reflexive thought, we can align our mental propositions with the ideal ones. The ultimate intellectual goal is this alignment of our thought with the eternal truths.
