That sensory input and beliefs do not constitute knowledge
Rene Descartes feared being misled by false beliefs or opinions. He was particularly concerned about being deceived by his senses, which led him to develop his method of doubt in his philosophical work.
Descartes doubts everything because he believes that our senses can deceive us, leading to false beliefs. He also questions the reliability of our thoughts and reasoning abilities. By doubting everything, Descartes aims to find a foundation of certainty that cannot be doubted.
Descartes' radical doubt refers to his method of systematically doubting all beliefs and knowledge in order to establish a foundation of certainty upon which to build his philosophy. By doubting everything that can be doubted, Descartes aimed to arrive at indubitable truths that could serve as a solid basis for his philosophical system.
René Descartes, a French philosopher, created the system of systematic doubt. In his work "Meditations on First Philosophy," Descartes employs the method of doubt to question all his beliefs in order to find a foundation of certainty in knowledge.

In Descartes' Meditations, doubt serves as a tool for philosophical inquiry by challenging and ultimately casting skepticism on the reliability of sense perceptions and beliefs. Through methodical doubt, Descartes aims to uncover indubitable truths and establish a foundation of certain knowledge upon which to build his philosophical system. Doubt, therefore, acts as a catalyst for Descartes' quest for certainty and the establishment of foundational principles in his philosophy.
The religious beliefs of René Descartes have been rigorously debated within scholarly circles. He claimed to be a devout Roman Catholic, claiming that one of the purposes of theMeditations was to defend the Christian faith. However, in his own era, Descartes was accused of harboring secret deist or atheist beliefs. Contemporary Blaise Pascal said that "I cannot forgive Descartes; in all his philosophy, Descartes did his best to dispense with God. But Descartes could not avoid prodding God to set the world in motion with a snap of his lordly fingers; after that, he had no more use for God."[24]Stephen Gaukroger's biography of Descartes reports that "he had a deep religious faith as a Catholic, which he retained to his dying day, along with a resolute, passionate desire to discover the truth."[25] After Descartes died in Sweden, Queen Christina abdicated her throne to convert to Roman Catholicism (Swedish law required a Protestant ruler). The only Roman Catholic with whom she had prolonged contact was Descartes, who was her personal tutor.[citation needed]
Rene Descartes was a 17th-century French philosopher, mathematician, and scientist known for his dualistic philosophy, which emphasized the separation of mind and body. He believed in the existence of innate ideas and the importance of reason and skepticism in philosophy. Descartes famously declared, "I think, therefore I am," highlighting the centrality of consciousness and self-awareness in his philosophy.
Rene Descartes believed in the existence of God but also emphasized the importance of reason and critical thinking. He argued that faith should be guided by reason and that individuals should not simply accept established beliefs without questioning them. Descartes saw religion as compatible with his philosophical system, with God serving as the guarantor of truth.
