The author, a Mexican philosopher, has the ability to make philosophy accessible by focusing on the essentials, using a clear and direct style, employing a linear and concise discourse, and following a structure that facilitates understanding. His approach is practical and philosophical, rooted in the Aristotelian-Thomistic tradition, but also enriched by the ideas of contemporary realist authors. His merit lies in maintaining the depth of his ideas while capturing the attention of an audience not necessarily familiar with the humanities.
The essay begins by emphasizing the importance of friendship and then explains what it is: an affective relationship between two or more people who understand each other, share interests, and help each other unconditionally. This idea is developed in the five chapters of the book: The Value of Friendship, Affective Affinity, Understanding Between Friends, Common Interests, and Interest in the Friend.
Among the most notable ideas are: having friends is one of the greatest treasures; many people do not have true friends; often, people do not understand what true friendship is, and therefore, do not practice it; sympathy without understanding is unstable; to achieve deep friendship, common interests are necessary; and the most important aspect of friendship is the interest in the friend, which involves a choice by the will, providing strength and consistency to the other aspects of the relationship.
There are particularly significant chapters, and it is recommended to spend more time reflecting on them to understand their implications: friendship is selfless and endures until death; friendship leads to union with God; love as the foundation of understanding; the weakness of objective affinity; the intervention of the will; and the greatest good for the friend.
This book is highly recommended for those who wish to improve the quality of their friendships and increase their number. It can be enjoyed by a diverse audience, from young people to older adults.
