  The idea of the success condition is that one puts one's knowledge into practice.  Or, rather than using the terminology of success, one might require that a wise person's beliefs and values cohere with one's actions (Tiberius, 2008).  The main idea is that one's actions are reflective of one's understanding of what it means to live well. A view along the lines of (KLS) would be embraced by Aristotle and Zagzebski (for practical wisdom), and by Kekes, Nozick, and Tiberius. (KLS) would not be universally embraced, however (see Ryan 1999, for further criticisms).  One criticism of (KLS) is that one might think that all the factual knowledge required by (WFK) is missing from this theory. One might argue that (WFK), the view that a wise person has extensive factual knowledge, was rejected only because it did not provide sufficient conditions for wisdom. Many philosophers would claim that (WFK) does provide a necessary condition for wisdom. A wise person, such a critic would argue, needs to know how to live well (as described by Nozick), but she also needs to have some deep and far-reaching theoretical, or factual, knowledge that may have very little impact on her daily life, practical decisions, or well being. In the preface of his Principles of Philosophy, Descartes insisted upon factual knowledge as an important component of wisdom. Descartes wrote, “It is really only God alone who has Perfect Wisdom, that is to say, who has a complete knowledge of the truth of all things; but it may be said that men have more wisdom or less according as they have more or less knowledge of the most important truths” (Principles, 204).  Of course, among those important truths, one might claim, are truths about living well, as well as knowledge in the basic academic subject areas.
