We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.
I am certain that the Lord, who notes the fall of a sparrow, looks with compassion upon those who have been called upon to part, even temporarily, from their precious children.
