Adam is a strong, intelligent, and rational character possessed of a remarkable relationship with God. In fact, before the fall, he is as perfect as a human being can be. He has an enormous capacity for reason, and can understand the most sophisticated ideas instantly. He can converse with Raphael as a near-equal, and understand Raphael’s stories readily. But after the fall, his conversation with Michael during his visions is significantly one-sided. Also, his self-doubt and anger after the fall demonstrate his new ability to indulge in rash and irrational attitudes. As a result of the fall, he loses his pure reason and intellect.

Adam’s greatest weakness is his love for Eve. He falls in love with her immediately upon seeing her, and confides to Raphael that his attraction to her is almost overwhelming. Though Raphael warns him to keep his affections in check, Adam is powerless to prevent his love from overwhelming his reason. After Eve eats from the Tree of Knowledge, he quickly does the same, realizing that if she is doomed, he must follow her into doom as well if he wants to avoid losing her. Eve has become his companion for life, and he is unwilling to part with her even if that means disobeying God.

Adam’s curiosity and hunger for knowledge is another weakness. The questions he asks of Raphael about creation and the universe may suggest a growing temptation to eat from the Tree of Knowledge. But like his physical attraction to Eve, Adam is able to partly avoid this temptation. It is only through Eve that his temptations become unavoidable.
