Final answer:
According to Abraham Maslow's hierarchy of needs, self-actualization is the highest need. However, later in his life, Maslow added a level above this, called self-transcendence, which is now considered the ultimate highest need.
Step-by-step explanation:
According to Abraham Maslow, a person's highest need is the need for self-actualization. This concept is derived from Maslow's hierarchy of needs, where self-actualization represents achieving one's full potential and is placed at the top of the needs pyramid. However, later in his life, Maslow proposed an additional level above self-actualization, which is self-transcendence. Self-transcendence refers to the striving for meaning and purpose beyond the self, including experiences like making self-sacrifices to improve the conditions of others or to make a political statement.
While self-actualization focuses on personal growth and fulfilling one's own potential, self-transcendence encompasses a broader scope that extends beyond individual concerns, involving a deeper connection to others, nature, or a higher purpose. Therefore, considering the complete scope of Maslow's work, the highest need after his revision is self-transcendence.
