How did the enlightenment change basic western attitudes toward faith, reform, and reason?

The Enlightenment philosophy engaged the idea that man was generally 'good' and that this 'goodness' would govern his decision making abilities. Those who adopted an 'enlightenment philosophy' believed that they had the capacity to reason and therefore were entitled to autonomy over their lives. Enlightenment thinkers believed that they themselves were capable of reforming the society they lived in and it did require permission from the church. This new belief flew in the face of religion, namely the authority of the Roman Catholic Church. As a result, many enlightened thinkers moved away from the absolute obedience the church required of them and instead adopted a Deist philosophy. Those who considered themselves Deists believed in a higher or supreme being however were free to worship as they saw fit. They viewed the Roman Catholic Church as an institution that lost its revelance in the new scientific, philosophical world they lived in. The rules and requirements the church 'forced upon the sinning masses' simply went against the idea that people were generally good.
