Delving into the Philosophical Basis of Existentialism's Core Beliefs

In the realm of philosophy, a shift in thinking has taken place, challenging the traditional understanding of knowledge and its origins. This shift is known as existentialism, a movement that prioritizes subjective, individual experience and freedom as the basis of knowledge and meaning.

At the heart of this change lies epistemology, a branch of philosophy that investigates the nature, scope, and origins of knowledge. Traditionally, epistemology has sought objective, universal knowledge, often grounded in reason or experience. However, existentialism offers a more nuanced, human-centered understanding, rejecting the impersonal, objective knowledge that traditional epistemology seeks.

Søren Kierkegaard, often considered a precursor to existentialism, emphasized subjective experience and the "leap of faith" in relation to truth. He argued that truth is not merely an abstract, rational concept but something lived personally and passionately; truth is subjective and must be appropriated by the individual inwardly.

Friedrich Nietzsche challenged traditional epistemology by rejecting absolute moral truths and rationalism. He highlighted the perspectival nature of knowledge and the role of power, will, and creativity in shaping values. Nietzsche’s emphasis on the "will to power" and the creation of individual values "beyond good and evil" entails that knowledge is always tied to the interpretation and valuation by the individual rather than objective universals.

Jean-Paul Sartre extended existentialism's core principle that existence precedes essence, focusing on radical freedom and responsibility. For Sartre, knowledge is grounded in individual consciousness and freedom of choice; human beings must actively project themselves into the world and define their essence through decisions and actions.

Martin Heidegger, while linked to existentialism through his concept of "being-in-the-world" (in-der-Welt-sein), shifted the focus to ontology—the study of Being itself—as a precondition for knowledge. Heidegger argued that traditional philosophy overlooked the fundamental question of what it means to be. Instead of treating knowledge as detached or purely objective, he emphasized that human being is always already engaged and situated in a world, and understanding arises from this primordial context rather than abstract theorizing.

This shift reflects existentialism's broader rejection of detached epistemic certainty for a dynamic, situated, and self-constituted approach to knowledge. Knowledge, according to existentialism, is deeply rooted in personal experience, emotion, and context. Existentialism challenges the primacy of rational thought in the acquisition of knowledge, emphasizing that emotions, intuition, and lived experiences are essential to understanding.

The awareness of our own finitude—our eventual death—forces us to confront the limitations of our knowledge and compels us to seek knowledge more urgently, to live authentically, and to embrace the finite nature of our existence. Authenticity plays a central role in existential epistemology, requiring individuals to confront uncomfortable truths and take responsibility for their lives.

In conclusion, existentialism offers a refreshing perspective on the nature of knowledge, one that is deeply rooted in human experience, emotion, and freedom. It challenges traditional epistemology's pursuit of objective, universal knowledge, instead emphasizing the subjective, personal nature of understanding. This shift towards a more holistic, dynamic, and self-constituted approach to knowledge reflects the complexities and uncertainties of life, reminding us that while we may never have complete or absolute knowledge, the search for meaning and understanding is a crucial part of what it means to be human.
