From Man as Predator to Man as Giver. Reflections on the Gift and the Self-Giving in Psychology


Considering the values and the cultural model today prevailing, all centred on narcissistic individualism and extreme competition, Chiara Lubich’s thought on gift and self – giving is likely to look ingenuous and absurd. However, this thought is confirmed in the secular culture of today and in particular in the psychological studies.
