I recently learned about the existence of solipsism. it turns out that this is the theory that nothing exists but yourself. in my opinion, this is either a psychological defensive reaction to a stimulus that environment acts as ,or a way of self-expression which is designed to increase self-esteem and distract a person's attention from what he can not accept. It seems that solipsism is closely related to another form of psychological defense - denial. in my opinion, solipsism with its categorical denial can provoke the appearance of schizophrenia or accentuation associated with the pre-stage of schizophrenia and the loss of the ability to perceive reality. Some studies have criticized solipsism as an illogical form of philosophy. after all, how can a person exist in a space that does not exist? I hope,I didn't blow up anybody's mind
