Growing uncertainty in the modern age among people drives researchers to address this problem and come up with meaningful solution. In this regard Existentialism plays the substantial role to make people aware about their abilities to know who they are and what they must do in order to overcome modern challenges which hunt them with equal intensity. This study is being conducted from the work of two most influential Existentialists Soren Kierkegaard and Jean Paul Sartre and to know their existentialist approach collectively. They both have worked a lot on the Existentialism. To identify their existentialist approach, the qualitative method is taken into consideration through that the textual analysis would be carried out by picking up few chapters from the written works of Kierkegaard and Sartre and the comparative analysis is being done very closely and with great attention and care. However, the result of the study is this that they both talk about individual freedom but their approach and ways look different. Kierkegaard seems more religious and the major point that Kierkegaard proposes a man must know “what he has to do? Not what he has to know?” it shows that how much practical He is in his Existentialist Approach. This type of understanding and awareness precedes the actions. The point is here to identify thyself and what really God wants from us to do? Kierkegaard emphasizes on the subjective truth and absolute can be obtained through subjectivity not objectivity; whereas Sartre is more outspoken and talk about Existentialism openly and widely. Sartre believes in freedom of intention not freedom of successful actions. He considers himself “the Existential Atheist”, and his famous phrase is “Existence precedes and governs the Essence”. Here Existence implies for subject and Essence highlights the object. So, the subjectivity of man always comes before the objectivity.
