Introduction
Definition of Epistemology
Epistemology is the branch of philosophy that investigates the conditions under which it can be acquired. As Mitchell (2018) states in Roots of Wisdom, “Epistemology studies the structure, sources, and limits of knowledge” (p. 22). Throughout history, one of the most significant philosophical issues has been epistemology.
The philosopher can engage in philosophical reflection only by examining knowledge, since their sole aim is to comprehend and understand reality. Everything, even “virtual reality in an environment created by a computer, “is perceived uniquely by each person (Mitchell, 2018). Having said that, everyone’s experiences cause them to hold distinct beliefs about reality and the human condition.
Knowledge About Truth
A central question of epistemology is how people can know something is true. Two thinkers who disagree on this question are the British Empiricists, represented by John Locke, and the Rationalists, represented by René Descartes. Thus, the essay aims to discuss current epistemological questions, considering the perspectives of Locke and Descartes.
John Locke’s Empirical Approach
Locke grounds the fundamental presuppositions of his epistemology on the presumption that man is a blank slate at birth and that experience is the key to knowing. He categorizes these experiences into inner and outward experiences and identifies the thoughts that are part of them (Janbozorgi et al., 2022). Locke’s argument for the empirical approach to knowledge is that the only source of knowledge is sense experience. He claims that since all knowledge of the world is derived from sense experience, we can only be certain of what we can observe directly (Janbozorgi et al., 2022).
Although this theory implies that everyone can learn the truth from experience, Locke ignores the fact of genetics, which lays the foundation for further knowledge. Locke believes knowledge is derived from experience, not innate ideas, reasoning, or deduction. Locke thought that without sensory experience, no perception of reality would be possible in an empty child’s brain. Consequently, he points out that comprehension would be impossible without critical sense perception.
René Descartes’s Rational Approach
On the other hand, Descartes argues that humans can know everything with certainty through reason alone. He claims that humans are born with innate ideas and knowledge, and that the truth of these ideas can be reached through deductive reasoning (Janbozorgi et al., 2022). Descartes believes that knowledge can be achieved through logical deduction and that any idea that can be logically deduced must be accurate. His strategy is to have a broad sense of skepticism about everything rather than trying to disprove common myths.
It is appropriate to use the term radical methodological uncertainty (Janbozorgi et al., 2022). Descartes is concerned that any presumption based on his experiences must be thoroughly questioned. He points out that most of what is based on sense stimuli is false and calls for rigorous, methodical questioning.
The weakness of Descartes’ theory is his recognition of the impossibility of human reason evolving in a way other than pragmatically. The theory fails to account for the nature of complex decisions arising from prior errors. Descartes’ theory is limited because it violates the sense of systematicity taught in any society. Descartes uses thought, forgetting that it has no time to form, but this does not diminish the need to go to it.
It is well known that this distinguishes Descartes’ systematic methodology. He outlines his approach to practice in his work on the subject. He believed that all we know is founded on archaic ideas. He aims to “rethink” the world using Enlightenment-era mathematical techniques.
Descartes seeks a reliable foundation, which he discovers in mathematics. His first guideline is that nothing that cannot be confirmed beyond a reasonable doubt should be accepted as accurate (Janbozorgi et al., 2022). The following premise concerns the deconstruction of the problem: it should be divided into smaller issues until straightforward structures emerge that can be resolved by intuition. He says those particular answers should be combined in the following stage. In the end, the question is whether this construct may be valid.
Comparison of the Perspectives
Both thinkers make compelling arguments, but Locke’s is stronger. Locke’s argument is deductive, logically following his premise that all knowledge is derived from sense experience. He argues that since we can only observe things through sense experience, knowledge of the world must be limited to what we can observe. Therefore, we cannot be certain that knowledge is not derived from sense experience.
Descartes’ argument is more of an inductive argument. He claims that we can know certain things with certainty through reason alone, but he never provides an example of how this is possible. He merely states that we have innate ideas, without providing any evidence to support his claim.
Conclusion
Thus, I believe the philosopher’s primary goal is to know and comprehend reality, and there is only one method to participate in philosophical reflection in the world: reflecting on knowledge. John Locke’s empiricism offers a stronger argument for the validity of knowing something. Locke’s argument is rooted in logical deduction, while Descartes’ argument lacks evidence and relies on unsubstantiated claims. This essay has explored how two prominent thinkers disagree on how we can know that something is true and which one has the stronger argument. However, many questions remain unanswered, such as how individuals can learn to develop more accurate methods of reasoning and how we can better distinguish between reliable and unreliable sources of knowledge.
