Meditations of René Descartes on First Philosophy is a philosophical work consisting of six meditations on things that Descartes establishes cannot be known with certainty, as well as attempts to establish all things that can be known without doubt. . Descartes was one of the first great Western philosophers to attempt to build a foundation of certainty about knowledge. Meditation The first concerns everything that can be identified as doubtful. Descartes explains how, as a child, he believed many false things. Descartes states that he must put an end to these false beliefs before he can acquire true knowledge. He goes on to explain that he doesn't exactly need to prove that his beliefs are false, but that he needs to convince himself to avoid having beliefs that aren't certain. He sincerely believes that he can find doubt in each of his false beliefs. Consequently, what Descartes accepted as truth, he learned from his senses, and the senses can often mislead one. Even if he believes that his senses can and do deceive him, there are still things that he does not allow himself to doubt, even if they were learned with these same senses. He has decided to forget everything he thinks he knows and start from scratch, rebuilding his knowledge on more precise justifications. Descartes thinks of the example of him sitting in front of the fire, wearing his winter dressing gown and touching paper. At first he suggests that there's no way to deny that he actually feels these things, and he knows it through his senses. He then wonders if he is dreaming, because in a dream you would think you would feel these things, but in reality you wouldn't. Descartes goes back and forth around dreams and realities...... middle of paper ....... In his head, by doubting everything, he can at least be sure not to let himself be deceived by this so-called demon.Meditation Skeptical doubts are presented as a question of examination in their own right. Skepticism is a frequently discussed and heavily debated topic in philosophy today. Descartes was the first to ask the confusing question of how we can claim to know with certainty anything about the world around us, and the thought of what knowledge or skepticism is. The idea is not that these doubts are probable, but that their possibility can never be totally ignored. If we can never be positive, we cannot pretend to know anything. Skepticism is an attempt to provide a specific and necessary basis for our knowledge and awareness of the world. Skepticism is often taken too far and seen as a challenge to humanity's very idea of ​​rationality..
