Every person is responsible for himself. In society, people are responsible for their actions; good deeds will lead to rewards while bad deeds will lead to demerits. Human beings live in a world where they are told what to do and how to do it, and where they have to deal with what is seen as right and what is seen as wrong, but ultimately, humans have free will to do what they want. they want and to do it. make their own choices, which leads them to be responsible for those actions. Every day, human beings are faced with these choices and decisions to make only to know deep down that they will have positive or negative reactions to their choices, and it is this key idea that led to a specific philosophical concept in the 19th century, l 'existentialism. . This philosophy can be clearly seen in everyday life as well as in theater movements of the past and present. Examining the works of Samuel Beckett will present evidence of existential thought that demonstrates the progress of this philosophical movement. It will illustrate how existentialism influenced Beckett, especially through his work Waiting for Godot. The Theater of the Absurd is another theatrical concept examined demonstrating that Samuel Beckett integrated philosophy into his works through the Theater of the Absurd. It will also be examined whether or not Beckett justified existentialism or reshaped the theory, especially through the expression "existence precedes essence", which will lead to the conclusion whether this philosophical concept was only seen as a movement through a time specific, or an exercise in daily life. Through examining existentialism and the idea that "existence precedes essence", it can be shown that this movement is still ongoing... halfway through the article ......mined and cited by different philosophical movements and theories, yet existentialism is a concept that can always be evident in Beckett's work. The Theater of the Absurd will always be associated with existentialism as they both revolve around human conditions and the meaning (or lack thereof) of life. Nowadays, it doesn't really matter whether you believe in the existence of God, or whether or not you understand and accept the meaning of life, but the general concept of existentialism is evident in everyone's life. People are responsible for what they do with their lives, every action has its consequences, and we exist first and it is our purpose to give meaning to our lives and become our own person.
