What is suggested to your attention is, in a sense, an invitation. To introduce the most interesting work of Erich Fromm: "The art of loving or exploring the nature of love." While reading this book, you are going to agree in some ways with its author, whereas in other ways you are not. In any case, you are not going to regret the time spent on reading it. In terms of a sense of pleasure received while reading and of benefits obtained from it. For your life.

"The art of loving" can be commented on or discussed, can be both and even more. We, in our turn, allowed ourselves only to make a very tiny description about rationality/irrationality of the phenomenon of Love.
