IntroductionSolipsism is a concept where it is believed that mind is the only existing thing and anything that exist out of mind is baseless. This philosophical theory is in favor of consciousness of an individual. It may seem silly, but it is true when some thought is put into it. It is not possible to verify anything except the consciousness of an individual. In this doctrine, the existence of a person means only his existence and only his mental state. It is related to the events, processes, people and physical objects present around a person. Key arguments in favor of this concept are discussed below.DiscussionIt is the argument in which the existence of anything is questioned. For a person, the existing things are the only ones that he experiences. Therefore, having a supposition that there are emotions, thoughts, and experiences other than his own is not possible for a solipsist. It is because he can attach no meaning to the thoughts and emotions of others. Even the social class to which a person belongs is a great determinant of his behavior because his perceptions are based on the material sources available to him (Kraus, Piff, and Mendoza-Denton). This state is mostly experienced by children because for them the only existing world is what is around them or what they know. It is commonly known as infant solipsism where the child does not have an idea that there is an outside world that exists.Sometimes this is also referred as a syndrome where the person suffering from it doubt others existence. The only things about which that person is sure about is his mind. This concept is metaphysical solipsism where the only reality is self. Gorgias of Leontini is known as the father of Solipsism, and he describes this concept in various ways. First, nothing exists other than the mind of an individual. Second, even if other things are existing, there is no fact about their existence. Third, even if there are facts about its existence, it is not possible to communicate knowledge about its existence. Fourth, even if there is a way to communicate, there is no way that it will be understood in the same manner (Waribugo and Eketu). This show that the concept of Solipsism is just an assertion. This assertion state that reality is just the self of a person and there can nothing exist outside of self.The human mind is the only existing reality, and nothing can exist unless the person is aware of its reality. Three major types of solipsism include epistemological solipsism, metaphysical solipsism, and methodological solipsism. Epistemological solipsism is the concept where reality is approximated, as it is the only mental state of the viewer. Metaphysical solipsism interpret the only source of reality is individual, and there is no existence of the outer world. Methodological solipsism views consciousness as the only basis for a reality where mental processes and self is the focus.The best way of explaining these concepts is through the example of hallucination. Whenever the person is hallucinating, he is convinced to the last extent that it is a reality. It happens because in his head he sees those things differently. However, in reality, these claims are not considered true because they are just in his head. Similarly, sensations are simulated in dreams of a person, and this is because what a person perceives is the things different parts of brain tell him to do. So, the sense of surety can only be provided through the thoughts of a person (Bach). Also, the people who pass their extended time in isolation start doubting the existence of the real world, and they suffer from solipsism syndrome. It shows that the picture of the world is nothing but a mere creation of their mind.A philosopher Berkeley has uniquely presented the idea of solipsism. For him, an object exists only if it is observed; otherwise, it is non-existent and meaningless. However, he does not believe in pure solipsism because for him there is the mind of God that is all-encompassing (Grey). In a context, solipsism is also categorized as something related to “private.” Now private has further two senses. One is privacy related to knowledge, while, another sense of privacy is related to possession. Solipsism is private in a sense where the person is the only individual who can know it. The experiences of a person can only be known to him, and only he can have possession of it. If the pain is taken as an example, other people can know about the feeling of pain, but they cannot have it.ConclusionSolipsism is a concept that face criticism from many disciplines of study. However, this is true that the contents of a mind are the only things that exist for an individual and there are shaped by the person’s own experiences and thoughts. However, there is no logical and conceptual link between the physical and mental states because mind only perceives what it knows. The privacy of a person is restricted to his experiences and thoughts only. All the arguments discussed above give clear proof that a person can never be sure about anything except the ones that exist in his intelligence.Works CitedBeck, K. “De re Belief and Methodological Solipsism,” in Thought and Object – Essays in Intentionality (ed.
