Existentialists believe that meaning is not something that is given or discovered, but rather something that is created through one's actions and choices. By living authentically and expressing one's true self, individuals can find meaning and purpose in their lives.

Martin Heidegger, a German philosopher, introduced the concept of "Dasein" or "being-in-the-world" to describe the unique way in which humans exist and experience the world. He believed that the meaning of life lies in understanding and authentically engaging with one's own existence.

Absurdism, as propounded by existentialist philosophers like Albert Camus, posits that the world is fundamentally meaningless and irrational, and that human attempts to find meaning and order are ultimately futile. However, individuals can find meaning and purpose by acknowledging and embracing the absurdity of existence.

Simone de Beauvoir, a French existentialist philosopher, argued that the primary obstacle to women's freedom and self-realization is not external factors like economic inequality or social oppression, but rather the internalization of societal expectations and norms that limit women's choices and opportunities.

Jean-Paul Sartre, a French existentialist philosopher, emphasized the importance of authenticity in meaningful action. He believed that individuals should act in accordance with their true selves and values, rather than conforming to societal expectations or external pressures.

Existential freedom, as understood by existentialist philosophers, is not simply the freedom to choose one's own actions, but rather the freedom to create one's own meaning and purpose in life. This freedom involves taking responsibility for one's choices and actions, and living authentically in accordance with one's values.

Aristotle, a Greek philosopher, believed that the meaning of life is to achieve "eudaimonia" or "flourishing". He argued that humans have a natural inclination to seek happiness and fulfillment, and that this can be achieved through living a virtuous life in accordance with reason and moderation.

Bad faith, as described by existentialist philosophers, encompasses all of the above options. It involves denying one's own freedom and responsibility, acting inauthentically or against one's true values, and avoiding confrontation with difficult existential realities such as death and meaninglessness.

Max Weber, a German sociologist and philosopher, introduced the concept of "vocation" or calling as a central aspect of meaningful action. He believed that individuals should seek to find their unique calling in life, which involves using their talents and abilities to make a positive contribution to society.

Existential anxiety, as understood by existentialist philosophers, encompasses all of the above options. It involves the fear of death and non-being, the fear of making the wrong choices, and the fear of losing control over one's life. These anxieties arise from the recognition of one's own freedom and responsibility in an uncertain and often meaningless world.

Friedrich Nietzsche, a German philosopher, believed that the meaning of life is to overcome the "will to power" and achieve a state of "amor fati" or "love of fate". He argued that individuals should embrace their own unique destiny and circumstances, rather than seeking to change or control them.

Meaninglessness, as understood by existentialist philosophers, encompasses all of the above options. It involves the recognition that the world and human existence may not have any inherent meaning or purpose, and that meaning is often subjective and varies from person to person.

Friedrich Nietzsche, a German philosopher, believed that the meaning of life is to create one's own values and live in accordance with them. He argued that individuals should reject traditional values and norms and instead create their own unique set of values that are authentic to their own lives.

Existential despair, as understood by existentialist philosophers, encompasses all of the above options. It involves the feeling of hopelessness and meaninglessness that arises from the recognition of one's own freedom and responsibility, the feeling of guilt and shame that arises from one's past actions, and the feeling of anxiety and fear that arises from the uncertainty of the future.

Jean-Paul Sartre, a French existentialist philosopher, believed that the meaning of life is to find one's unique "authenticity" or "true self". He argued that individuals should strive to live in accordance with their own values and beliefs, rather than conforming to societal expectations or norms.
