The term deism came up today – here is a definition:
Deism is the belief in a supreme being, who remains unknowable and untouchable. God is viewed as merely the “first cause” and underlying principle of rationality in the universe. Deists believe in a god of nature – a noninterventionist creator – who permits the universe to run itself according to natural laws. Like a “clockmaker god” initiating the cosmic process, the universe moves forward, without needing God’s supervision. Deism believes that precise and unvarying laws define the universe as self-operating and self-explanatory. These laws reveal themselves through “the light of reason and nature.”
