That man himself is capable of solving all his problems given enough time, wisdom, and scientific ability is the teaching of:

Wisdom.

Explanation:

Measurement of wisdom often depends on researcher's theoretical position about the nature of wisdom. A major distinction here concerning either viewing wisdom as a stable personality trait or rather as a context-bound process The former approach often capitalizes on single-shot questionnaires. However, recent studies indicated that such single-shot questionnaires produce biased responses., which is antithetical to the wisdom construct, and neglects the notion that wisdom is best understood in the contexts when it is most relevant, namely in complex life challenges. In contrast, the latter approach advocates for measuring wisdom-related features of cognition, motivation, and emotion on the level of a specific situation. Use of such state-level measures provides less biased responses as well as greater power in explaining meaningful psychological processes. Furthermore, a focus on the level of the situation has allowed wisdom researchers to develop a fuller understanding of the role of context itself for producing wisdom. Specifically, studies showed evidence of cross-cultural and within-cultural variability and systematic variability in reasoning wisely across contexts and in daily life.

Many, but not all, studies find that adults' self-ratings of perspective/wisdom do not depend on age. This belief stands in contrast to the popular notion that wisdom increases with age,. The answer to the question of age-wisdom association depends on how one defines wisdom, and the methodological framework used to evaluate theoretical claims. Most recent work suggests that the answer to this question also depends on the degree of experience in a specific domain, with some contexts favoring older adults, others favoring younger adults, and some not differentiating age groups. Notably, rigorous longitudinal work is necessary to fully unpack the question of age-wisdom relationship and such work is still outstanding, with most studies relying on cross-sectional observations.
