Fourthly, Nor demonstrative Knowldge.
      §4. Fourthly, It follows also, from what is above observed, that
our rational Knowledge, cannot reach to the whole extent of our Ideas.
Because between two different Ideas we would examine, we cannot
always find such Mediums, as we can connect one to another with an
intuitive Knowledge, in all the parts of the Deduction; and where-
ever that fails, we come short of Knowledge and Demonstration.
Locke Hum IV, 3, §4, p. 539
