Discussing Wisdom
Wisdom was always going to be a difficult chapter to write although it has much in common with knowledge from a writing perspective. Like knowledge, wisdom is not clearly defined and the title of 'wise' is often something that is bestowed on some unsuspecting and often unwilling person.
I do tend to discuss wisdom, at least in places, from personal experience. It is stressed that this is not a claim to be wise, it seems to me at least that the implication is an unavoidable but unwarranted aspect of discussing wisdom. The chapter asks what wisdom actually is and attempts to furnish existing explanations of wisdom. However, many of the existing explanations seems to relay on references to things that have been said and sometimes things which have been done rather than on people who have aspired to wisdom.
Although a definition for wisdom seems to be elusive, the chapter does tend to favour a particular set of properties which define wisdom. Towards the end of the chapter, the properties which may define a wise person are laid out. These properties are also used, I think effectively, to show that someone who did not possess the properties is unlikely to be considered to be wise.
