Wisdom comes from an awareness of the greater whole. The insights do not come from analysis, but rather, synthesis. It engages with the intuition rather than the intellect.
Although it can seem mystical, I think there are authors who have been able to express ways to engage in wisdom even if they are not directly talking about it. For example, Christopher Alexander has some interesting things to say about wholes, centers, and unfolding:
