The article suggests an ethical-anthropological reading of Thoughts, magna opera of the French mathematician and philosopher Blaise Pascal, which was published after his death by his relatives and friends. Such a reading is presented in three moments: Firstly, an anthropological description aimed at answering the question 'who is man?'; secondly, an analysis of Pascal's erotic condition; and, finally, an ethical proposal as cura amoris (care for love). The main argument of the article is that every human being has a motivation in acting, that of love and being loved. Thus, having a happy or unhappy life depends on the care for this erotic condition, and the latter is achieved through thought.
