Final answer:
Freud focused on the past and the personal unconscious as formative in human psychology, while Jung introduced the collective unconscious, suggesting that future potentialities also shape human behavior. This statement about their beliefs is true.
Step-by-step explanation:
Freud indeed viewed human beings as largely influenced by their past, especially by repressed memories and early childhood experiences. Hence, it is true.
Freud believed the unconscious mind was a repository for these repressed thoughts and feelings, emphasizing the struggle to reconcile one's desires with societal rules, leading to inner conflict and defense mechanisms.
On the other hand, Carl Jung, although recognizing the role of a personal unconscious similar to Freud's, also introduced the concept of the collective unconscious. Jung posited that human beings are not just shaped by their past but also by future potentialities, as the collective unconscious houses archetypes that influence behaviors and thought processes not limited to personal experiences.
