According to John Stuart Mill, tolerance is based first and foremost on the assumption of the importance of the autonomy of the individual. The main advantage of this tolerance is that it protects any particular opinion which would otherwise be in danger of suppression were it not for 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 blueprint for how to best live life. Rather, he argues that if a person is adequately developed, then his choices about how to live are the best precisely because they are his. However, in accordance with utilitarian principles, this assumption only goes so far as such choices do not directly diminish the pleasures of others or cause excess pain to them or themselves. To understand Mill's argument for toleration and why it involves no objective evaluation, it is very important to distinguish between applications of one's personal beliefs. For example, Mill argues that there should be no objections to a person's individual beliefs and opinions (freedom of conscience), but he believes there are some limits to how a person can act on those beliefs. These limits are established by the harm principle. Mill professes his belief in autonomy except when a person demonstrates endangering others by his or her actions; states that "no one pretends that actions should be as free as opinions." Mill does not believe that it is possible to make objective assessments of people's beliefs and lifestyles because beliefs do not have the potential to cause harm as actions do; every human being is the only one who feels his own body and knows his own mind intimately and directly. Furthermore, everyone… middle of paper… me who is not is to assume that we are infallible. Even false opinions can contain valid points and parts of truth; therefore, to know the whole truth we must weave together different sources of arguments. Above all, it is only in an atmosphere of free thought that an individual can acquire advanced consciousness. An 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 of more value to others", and in doing so states that to subscribe to an objective evaluation of a good life, is for Mill the equivalent of putting society on hold and preventing human beings from reaching the highest truth and therefore happiness.
