CoGiTic Evolution of Man 6^27 



that he could little if at all govern, that at times seemed to 

 benefit, at times seemed to injure him, all conspired to raise 

 sublime thoughts in him, and compelled him to reason on them. 

 In his effort then to build up ever wider proenvironal responses 

 to these expansive environal stimuli that stirred his highest 

 brain centers, man had thus presented to him wide and lofty 

 ideals, that in their practically infinite scope caused him to 

 aspire, to proenviron ever higher, further, and more earnestly. 

 Thus originated in time deep spiritic longings, a desire to com- 

 prehend the source and the working of that infinite energy 

 that seemed to move all things, but was itself elusive. And 

 so man became simultaneously the scientific and the religious 

 animal. 



He observed and thought more and more deeply and widely 

 on the physical and vital phenomena around him; and so the 

 discovered facts of law and order, in family life and heredity, 

 in seasonal change, in plant and animal life, in the winds, the 

 sunshine, the snow, the rain, or in the heavenly bodies, became 

 at first crude, but in time accumulating scientific knoicledge. 

 The reverence he showed, the submission of his knowledge and 

 will to a greater Power, the longing desire to become one with, 

 or on reverential terms with that Power, developed religious 

 aspirations, the unfolding of which in human history is sketched 

 in a subsequent chapter, and the phases of which, when fol- 

 lowed in a pure and reverential frame of mind, have immensely 

 helped to raise man above "the brutes that perish." 



The brain centers that were mainly concerned in this eleva- 

 tion of man to high estate seem to be the deepening and com- 

 plicated convolutions of the frontal cerebral lobes, and refer- 

 ence is made to these elsewhere (p. 684). 



In concluding this chapter then, we would venture to assert 

 that all molecular organization, from the simplest gaseous and 

 liquid compounds, up to the most comj)lex colloid cerebral 

 constituents of man, is evidently the result of integrating 

 physico-chemical force, or energy-exhibition. And so the all 

 important consideration in such integration is not the purely 

 chemical side of the question, as has too often been considered
