In Freudian theory, Eros represents the life instinct or the drive for love, creativity, and self-preservation. It is associated with positive energy and the urge for connection with others. Thanatos, on the other hand, symbolizes the death instinct or the drive towards aggression, destruction, and self-destructive behaviors. It is linked to negative impulses that can manifest as violence or self-harm. Freud believed that these two forces are in constant conflict within individuals, shaping their behavior and personality.
