to understand how the brain works". In addition, in our minds, we have developed models of others as "conscious agents". When person A talks to person B, B does not have the access to A's inner thoughts; however, B is able to gain a good sense of what's going on in A's mind and at the same time, A is able to convey such good ideas as well. Dennett says, "Your consciousness is my user illusion of you and my consciousness is your user illusion of me." Meanwhile, humans have the model of oneself as well. Just as how A would approach B, by asking A him/herself questions and waiting for his/her own responses, A can get access to him/herself as well such that we are probing our minds and getting ourselves to think and not think things as we wanted. By user illusion, we are manipulating our own brains. Evolutionary Fitness User illusion may have originated due to the selective pressures of Darwinism. Donald Hoffman explains how, most typically, the classic argument is that evolutionary fitness was correlated with perceiving the truth about our environment. Yet, he argues that the fitness function is not correlated with objective truth at all. According to Hoffman and colleague Chetan Prakash, “According to evolution by natural selection, an organism that sees reality as it is will never be more fit than an organism of equal complexity that sees none of reality but is just tuned to fitness. Never.” Hoffman explains that evolution has molded us to have perceptions and conscious experiences that allow us to survive and reproduce. Much like the computer desktop, our perception of reality is merely a tuned simplification that guides adaptive behavior, a user illusion. Responses to User Illusion Criticism Critics of user illusion argue that humans are able to access the content of their brain’s representations by introspection and analysis of inner speech. These critics point out that more often humans know what is meant, although they may be wrong about what they said or how they delivered what they said. Furthermore, critics argue that inner speech episodes permit access to the content of some of our brain states, which thereby allows us to know what our brain states represent by introspection. This argument refutes the claim that consciousness is merely a simplified representation of the world in which we cannot access the full information of reality since
