Psychology Book - The walls that separate men do not reach to the sky

We build walls around ourselves to protect ourselves. But these walls can become a windowless prison where life can no longer circulate or breathe. How can we respect each other without losing the sense of the universal and without losing the flavor and fruitfulness of the encounter? This book is a delicate and subtle invitation to reflect on the way in which our desire for truth, our quest for identity or the defense of our values can become a source of relationship rather than division, provided that we break down certain mental barriers.
