What is the difference between Deleuze's and Zizek's understanding of "love"?

Deleuze and Zizek are both important thinkers in the field of contemporary philosophy and cultural theory, and their understanding of love is different.

Deleuze believes that love is a perceptual force, which is composed of the relationship between individuals, creative and changeable. In his view, love should not be understood as a stable emotional state, but an eternal flowing state, which is manifested in a constantly changing situation. Deleuze believes that love is a free choice and a relationship between individuals, not defined by external norms. In Deleuze's view, love is a force of diversity, creativity and variability. It is not only an emotional experience, but also the basis of human social relations.

Zizek believes that love is an ethical concept that transcends emotion. In his view, love is the subject's commitment to the object and the responsibility and obligation under the ethical norms. Zizek believes that true love is not based on personal feelings, but on the ethical responsibility to the "absolute other". He believes that this kind of love transcends personal feelings, is a moral concept to a higher level, and is established for the common interests and happiness of mankind. In Zizek's view, true love is an ethical concept with ethical nature, which can transcend emotion.

Generally speaking, Deleuze and Zizek have some differences in their understanding of "love". The former pays more attention to the emotional relationship and creativity between individuals, while the latter emphasizes the responsibilities and obligations under ethical norms.
