According to John Stuart Mill, toleration is based primarily on the assumption of the importance of the autonomy of the individual. The main advantage of this tolerance is that it protects each particular opinion which would otherwise be at risk of being suppressed without the tolerance. By practicing tolerance in society, Mill believes that one can achieve the greatest happiness and therefore the best lifestyle. However, he doesn't believe there is a single model for living your best life. Rather, he argues that if a person is sufficiently developed, then his choices about how to live are the best, precisely because they are his own. However, in accordance with utilitarian principles, this assumption only goes so far as these choices do not directly diminish the pleasures of others or cause excess pain for them or oneself. To understand Mill's argument for toleration and why it does not involve any objective assessment, it is very important to distinguish between applications of one's personal beliefs. For example, Mill argues that there should be no objection to a person's individual beliefs and opinions (freedom of conscience), but he believes that there are certain limits to how a person can act based on these beliefs. These limits are established by the harm principle. Mill professes his belief in autonomy, except when a person proves that they endanger others through their actions; he states that “no one claims that actions are as free as opinions”. Mill does not believe it is possible to make objective assessments of people's beliefs and lifestyles, because beliefs do not have the potential to cause harm the way actions do; each human being is the only one who feels his own body and knows his own mind intimately and directly. Also, everyone... middle of paper... me, they aren't, it's assuming we are infallible. Even false opinions can contain valid points and parts of the truth; therefore, to know the whole truth, we must bring together different sources of arguments. More importantly, only in an atmosphere of free thought can an individual achieve advanced consciousness. Advanced consciousness is necessary for individuals to understand that they must work hard to find the truth; the truth to which only tolerance can lead. Mill says: "In proportion to the development of his individuality, each person becomes more valuable to himself and is therefore capable of being more valuable to others", and in doing so he asserts that to subscribe to an objective assessment of a good life, is for Mill, the equivalent of taking a break from society and preventing human beings from achieving the highest truth and therefore happiness..
