Summarise the following

"Freud came to believe that all behaviour is determined by innate sexual
and aggressive impulses. As these impulses are forbidden and punished
in society, they are pushed down (repressed) into the unconscious. But
these impulses do not disappear from the unconscious; they continue to
influence our thoughts, feelings and behaviour. As a result, we develop
and use defence mechanisms to try to manage the anxiety that these
unconscious impulses cause us."

Freud believed that behavior is determined by innate sexual and aggressive impulses that are repressed into the unconscious due to societal restrictions. These impulses continue to influence our thoughts and behaviors, leading to the development of defense mechanisms to cope with the anxiety they cause.
