Is the virtue of temperance in your character?
With virtue of knowledge, we include most of the intellectual virtues: scientia, as the identification of axioms and supreme principles that provide unity and harmony to all things; art, as the ability to produce something with our hands; intellect, as the intuitive process that allows us to deduce/induce universally valid truths from observation; wisdom, as scholarly intelligence that gives lasting insight into the most important causal relationships; and prudence, as the acquired characteristic of choosing the correct course of action (prudence is both a cardinal virtue and an intellectual virtue).
We also find curiosity, as a disposition to wonder, ponder, and inquire; intellectual humility, as a willingness to own up to one’s intellectual limitations and mistakes; and intellectual autonomy, as a capacity for active, self-directed thinking. Attentiveness is included, as a readiness to be personally present in the learning process; intellectual carefulness, as a disposition to notice and avoid intellectual pitfalls and mistakes; and intellectual thoroughness, as a disposition to seek and provide explanations.
Also worthy of inclusion are open-mindedness, as the ability to think outside the box; creativity, as the commitment to filling the void and ordering the chaos in new ways; intellectual courage, as a readiness to persist in thinking or communicating in the face of fear of embarrassment and failure; and intellectual tenacity, as a willingness to embrace intellectual challenge and struggle.
Does this describe you? If so, well done, you are a person of knowledge.
The opposing vices
The vices that oppose knowledge are simple-mindedness, disregard for beauty, foolishness and resistance to novelty. There are also intellectual vices, such as intellectual pride, intellectual dependency, superficiality and distraction.
Do any of these describe you? If they do, and if your score in the Virtue Test was low in this virtue, then you may want to choose to work on the virtue of knowledge in your character.
