Science is communal cognition, which aims at learning a Truth independent of anyone’s and everyone’s belief, and takes on theories as provisional steps in that general direction. Religion might be defined as communal practice, or the practice of community; a religious belief is real to the extent that it actually guides interpersonal practice.
Science is the quest for truth, which can only be recognized by the consensus of the community. Religion is the aspiration to a higher connectivity, through recognition and practice of the deeper connections between beings. The tension between them is rooted in the difference between two modes of experience, which we might call observation and immersion. Both can be distorted by special interests or by adherence to habits of practice which obstruct recognition.
