Those who have a propensity to philosophy, will still continue their researches; because they reflect, that, besides the immediate pleasure attending such an occupation, philosophical decisions are nothing but the reflections of common life, methodized and corrected.

All deliberations in life regard the former; as also all disquisitions in history, chronology, geography, and astronomy.
In some cases at least, these built-in structures will degenerate unless appropriate stimulation takes place at an early stage in life, but although such experience is necessary to permit the innate mechanisms to function, there is no reason to believe that it has more than a marginal effect on determining how they function to organise experience.
For the present, it seems that most complex organisms have highly specific forms of sensory and perceptual organisation that are associated with the Umwelt and the manner of life of the organism.
