"Intelligence and spirituality share features with wisdom, but they are not the same thing. One can be intelligent, yet lack practical knowledge. Spirituality is often associated with age, like wisdom, but most researchers tend to define wisdom in secular terms, not spiritual."
To break that down:
- It is uniquely human.
- It is a form of advanced cognitive and emotional development that is experience-driven.
- It is a personal quality, albeit rare.
- It can be learned, increases with age and can be measured.
- It is probably not enhanced by taking medication.
