|"The frog in the well" logic|
"The frog in the well" logic illustrates that a frog residing in the atmosphere and boundary of a well cannot imagine the length and breadth of the gigantic ocean. Such a frog, when informed of the gigantic length and breadth of the ocean, first of all does not believe that there is such an ocean, and if someone assures him that factually there is such a thing, the frog then begins to measure it by imagination by means of pumping its belly as far as possible, with the result that the tiny abdomen of the frog bursts and the poor frog dies without any experience of the actual ocean. Similarly, the material scientists also want to challenge the inconceivable potency of the Lord by measuring Him with their froglike brains and their scientific achievements, but at the end they simply die unsuccessfully, like the frog.
