"For one human being to love another, that is perhaps the most difficult of all our tasks, the ultimate, the last test and proof, the work for which all other work is but preparation."
(Rainer Maria Rilke)
"Beyond the element of giving, the active character of love becomes evident in the fact that it always implies certain basic elements, common to all forms of love. These are care, responsibility, respect and knowledge." (Erich Fromm)
