Cuba is changing because the political context of the island has changed with the retirement of Fidel Castro. There is a virtuous cycle in which less vertical relationships between the citizens and the state are emerging. These new types of links are the result of new attitudes among the population, but also of changes in several official policies.
The time has already passed of looking in dictionaries and manuals for a definition of what is a wise man. It is a person's art for polemics and controversy. I admire those who are capable of debating with their ideological opponents without falling into arrogance, verbal violence or personal offense.
