The title of this book highlights the characteristic of the author's production. "Studies" means research, contemplation, and theory, while the word "love" means a permanent event in human life, and a feeling that rational philosophy sees as a confused and ambiguous mixture about which it is not possible to conduct intellectual research. But the writer here fulfills the imperative duty he formulated: "Theory must open its clear eyes to subjective life from time to time. The viewer guesses and looks, but what he wants to see is life as it flows before him." In this study, the writer isolates the essence of love and purifies it, removing from it all the additions that obscure its realistic nature and complicate its process. It is love explained based on psychological and phenomenological research at the same time, and even on social research, since choice in love is considered one of the most effective factors in history.
