-7402 The Polar Organization of Animals. [ May, 
mankind, and certainly not as yet disproved by the advocates of — 
the opposite opinion. 
We may further consider the relations of these two organic 
poles. The energies and substances: organized in the body are 
not those which originally existed there. They are derived from 
the exterior world, and the body acts as a machine for their ab- 
sorption and utilization. Food comes continually into the body, | 
to be used primarily for nutrition, and ultimately for reproduction — 
Motor energy comes continually into the body, to be used pri 
marily for animal activity, and ultimately for mental development. — 
Thus from the outer world food and force, matter and motion, — 
pour constantly into the body, where they are separately em- 
ployed, and their excess directed to the two poles, food to the — 
reproductive, force to the mental pole. At these two poles they 
are organized and exist as separate organisms, nourished by the — 
body but not forming integral parts of it, the one fed with n 
ter, the other with motion, and the body acting as an intermedium 
to absorb matter and force from outer nature, and apply henii 
the uses of its two diverse offspring. T 
The above consideration leads to still another. It has beet | 
frequently assumed that the animal body is organized solely u 
der the influence of its external surroundings, and that its mE 
is a result of a varied series of adaptations to outer o 
But if our premises are correct there must be an inner "a

clared and energetic as the animal reaches a higher stage" 
development. The rhizopod is not a mere creature of outer T 
fluences. It has, in virtue of the conditions of existence of e 
toplasm, the two polarities mentioned. Though acted upon 7 
outer force, it reacts upon this force. Its lateral or sexual ge

These influences act vigorously throughout t kai 
animal evolution as internal molding forces, resisting OF pS ee 
the influences of the external molding forces. In the booy g
