deism is the philosophical belief which posits that although god exists as the uncaused first cause, responsible for the creation of the universe, god does not interact directly with that subsequently created world. the deists, differing widely in important matters of belief, yet agreed denying the significance of revelation in the old and new testaments. they either ignored the scriptures, endeavoured to prove them in the main by a helpful, or directly impugned their divine character, their infallibility, and the validity of their evidences as a complete manifestation of the will of god. deism manifested itself principally in england towards the latter end of the seventeenth century.
