In recent years, the sciences of psychology, anthropology, neuroscience, and biology have added to the understanding the concept of love.
Helen Fisher, a leading expert in the topic of love, divides the experience of love into three partly overlapping stages: lust, attraction, and attachment.
Love is a variety of different emotional and mental states, typically strongly and positively experienced, that ranges from deepest interpersonal affection to simple pleasure.
Unrequited love refers to those feelings of love that are not reciprocated.
Interpersonal love is most closely associated with interpersonal relationships.
Love in its various forms acts as a major facilitator of interpersonal relationships and, owing to its central psychological importance, is one of the most common themes in the creative arts.
The word "love" can have a variety of related but distinct meanings in different contexts.
If sexual passion is also involved, then this feeling is called paraphilia.
