A discussion of truth and epistemological theory is what Problems in Philosophy deliberates on. Using analytical methods, Bertrand Russell distinguishes society's judgments about reality. Using radical Cartesian doubts in the introduction, Bertrand Russell focuses on society's knowledge of the physical world. Bertrand shares his beliefs about the table in his room, how he understands through his beliefs, and what kind of thing the table is to Bertrand. He notes that his table is made of matter and that there is a way to possess knowledge of it. Bertrand says that seeing his table implies becoming aware of something, of an oval brown spot that he calls “sensory data”. Then, sensory data should be considered as a sign of the existence of physical objects, and from experience, to arrive at the physical world, society practices a rational inference process.

Get the original essay Unlike idealism, Bertrand justifies the reality of the particular and the universal using a view asserting that what is known to exist must also be, in a sense, something mental. . Universals are used to summarize details that are tangible things and found in one place at one time. Universals are characteristics such as whiteness or relationships that allow Russell to have causal, temporal, and spatial relationships. However, while idealists worry about most things, Russell claims that they equate the “object” of sense data with the “act” of sensation. Russell believes he knows his sensory data through knowledge and his table, a physical object important through its description. This differentiates between knowledge by description and knowledge by acquaintance. He states that we only learn our sense data automatically and therefore have direct knowledge. There are two types of terminology used in the theory of descriptions used for an object, their name and their defined definitions. The main example given earlier by Russell is "Bismarck" or "the first chancellor of the German Empire". By using definitions, we will identify and appreciate things that we do not recognize, allowing us to have indirect knowledge of things. Through the theory of truths, Russell supports our natural tendencies and discusses intuitions. Thus, facts, propositions and finally complexes containing universals with particulars are the logical construction intrinsic to Russell's theory. There are truths that we usually think about: they lie outside of human consciousness. Ideas, particulars, and universals are connected in ideas through propositions, which is an indication of a complex philosophical concept of meaning. The use of propositions generally incorporates statements about objects and the connections between them. If properly structured with particulars and universals, a proposition will constitute knowledge. This type of relationship is evident in Russell, but it can be complicated in technical terms. According to Russell's philosophy, a real proposition is a relation between a belief and a truth. In the book there is an apparent theme that often provides an important account of a priori knowledge. Russell supports a Platonic approach to universals that are more like Platonic “ideas.” He further states that it is possible not to understand a..
