Bacon's thinking was very practical and utilitarian in nature, although he seems to have been pessimistic as to whether or not human progress was really possible.
At least on the surface, Bacon professed allegiance to Christianity and belief in Christian doctrines, but it is uncertain as to whether or not that was really his true position. Regardless, in his efforts to dethrone scholasticism, he argued for a complete separation of reason and revelation (as part of a general separation of reason from personal interest, social conventions, human passion, etc.).
Bacon believed that this separation would facilitate the development of science, and he was right. But, once widely adopted, it also lead to the eventual separation of church and state, religion and morality, and more. Thus, Bacon's philosophical work was an important foundation for modern, rationalistic, skeptical atheism.
