This is a work on the work of Adam Smith. It is not an exhaustive or exegetical analysis of his work, but rather a reading around two major themes: wealth and power, for the purposes of which his "Inquiry into the Nature and Causes of the Wealth of Nations" has been taken as the basic text. From there, a series of definitions of wealth and its relation to power have been extracted. Each of them gives rise to a chapter in which the meaning of the definition as well as its context are discussed, and then some conclusions about it are proposed. Although the general hypothesis of this essay sustains that there is a constant causal relationship between wealth and power, the treatment of the subject, for reasons of exposition, will be done separately, beginning with the definitions of wealth, considering that Adam Smith is considered one of the most important sources for the formation of modern economic theory.
