In Walter Isaacson's biography of Benjamin Franklin, the author highlights Franklin's pragmatic approach to theology and belief. Franklin believed that engaging in spiritual debates or theological questions was pointless without empirical evidence to support any opinion. He preferred a rational understanding of the world based on observation and experimentation.

Franklin viewed concepts like divine intervention more as phenomena to be explored scientifically rather than subjects for theological contention. In his mind, even events thought to be miraculous should be approached with curiosity and tested like any other natural occurrence, reflecting his dedication to empirical inquiry.
