Descartes’ ideas about thinking and knowledge give us a different way to see how we understand the world. He believed that using our minds and thinking deeply is a better way to know things than just relying on our senses.
For a long time, people thought our senses—like seeing, hearing, and touching—were the best ways to learn about the world. Many philosophers and scientists believed that observing our surroundings was the foundation of all knowledge. But Descartes disagreed. He thought that our senses could trick us and give us false information. One of his famous sayings is, "I think, therefore I am." This means that the act of thinking proves we exist. Even when we doubt everything, just thinking is a sure way to know something is real.
Descartes argued that we should be careful about what we trust from our senses. In his book, "Meditations on First Philosophy," he used a method called skepticism. This means he tried to doubt everything possible until he found something he couldn’t doubt. This led him to question not only how reliable our senses are but also whether the outside world really exists or if it could all be an illusion.
One of the most known examples he used to show the problems of relying on our senses is the idea of an “evil demon.” In this thought experiment, he imagined a powerful force that could control our perceptions, making us believe things that are not true. This shows that while our senses can be fooled, our ability to doubt and think critically is something that cannot be manipulated. The very act of doubting proves that we exist and that our reasoning is crucial for gaining real knowledge.
Descartes believed that logical thinking and math are much more reliable than sensory experiences. While our senses might deceive us, the rules of math and logic remain steady. For example, he said that when you put a stick in water, it might look bent, but the actual position of the stick hasn’t changed. Math is true and doesn’t depend on what we see.
He also used a piece of wax in his explanations. When he heats wax, it changes color and shape, but it is still the same wax. Even if our senses see the changes, our ability to understand that it remains the same substance is an example of how our mind can see beyond our senses. This shows that reasoning can help us understand more about reality.
Descartes’ ideas were built on the notion that some basic beliefs are certain and can be trusted. He believed that strong ideas based on reason should be the foundation of all knowledge. He shifted our focus from seeing things around us to thinking deeply about them. For Descartes, reasoning acts as a solid base that supports all knowledge.
Even though Descartes' ideas provide a strong way to understand knowledge, some people have debated them. Critics say that by outright dismissing sensory experience, Descartes overlooked the important role our experiences play in learning and the scientific method. Other philosophers, like John Locke and David Hume, argued that understanding starts with our senses and that we learn by interacting with the world. This debate between rationalism (favoring reason) and empiricism (favoring experiences) has shaped many discussions in modern philosophy.
Even so, Descartes makes us think about how reason and experience work together. While it’s true that our senses can mislead us, concentrating only on rational thought can also create ideas that feel disconnected from real life. The challenge is to find a balance—appreciating both logical thinking and the useful information our senses bring.
Descartes also delved into bigger questions about existence. He suggested that by using our reason, we could understand truths about God and the relationship between our minds and bodies. He believed that something perfect must come from something outside of ourselves because imperfect beings cannot create perfection. This ties together what we know (epistemology) with what exists (ontology) and shows that reasoning can help us understand not just knowledge, but existence itself.
To sum up, Descartes’ emphasis on reasoning highlights the limits of trusting our senses when looking for knowledge. His critiques and examples, like skepticism and the wax analogy, reveal the weaknesses of sensory information while showing that rational thinking leads us to certainty. By making reason the center of how we gain knowledge, Descartes laid important groundwork for future thinkers and deeper discussions about what knowledge really means. While he started important conversations, the ongoing debate between rationalism and empiricism continues to enhance our understanding of how humans think and learn in philosophy.
