Final answer:
Freud believed that the desire for love is a result of our inherent irrationality driven by the unconscious pursuit of pleasure and potentially obsessive behaviors linked to the id's basic drives.
Step-by-step explanation:
According to Freud, we desire love because we are inherently irrational. Freud's theory of personality suggests that human behavior is largely influenced by unconscious motives. The id, which is one of the three aspects of our personality structure along with the ego and superego, operates on the Pleasure Principle and seeks immediate gratification through pleasure-seeking and aggression, often in ways that may seem irrational to our conscious minds. Thus, our longing for love, according to Freud, could be an expression of the id's pursuit of pleasure ('eros') as well as its drive towards obsessive behaviors.
While Freud emphasized the unconscious aspects and biological drives, Adler introduced the concept of conscious motivation, pointing out the importance of societal tasks such as forming intimate relationships. However, whether driven by conscious or unconscious motivations, forming connections with others can be seen as a fundamental human motivation, as suggested by Baumeister and Leary, and plays a crucial role in the development of our personality and fulfillment of our social needs.
