@carlos84 from the biological point of view, reason as the evolutionary basis of thought has consolidated the different ideologies and religions, to the point of creating ruptures in the relationship between cultures and between people of the same social class. In this situation, the ideal is to build bridges of understanding "between two positions", and reach consensual agreements, an element that undoubtedly strengthens friendship. Thank you for sharing your point of view related to how to win friends and influence people by interpreting Dale Carnegie position.
