Liebe ist der Wunsch, etwas zu geben, nicht zu erhalten. Liebe ist die Kunst, etwas zu produzieren mit den Fähigkeiten des andern. Dazu braucht man von dem andern Achtung und Zuneigung.
Love is the desire to give something, not to get it. Love is the art of producing something with the capabilities of the other. For that you need the respect and affection of the other.
May I suggest these changes to make it sound more natural in English. 1. Producing something with the capabilities of the other person/other people/others (plural form) For that you need their respect and affection. This solves the use of "other". Just my suggestion.
