All evolutionary creature life is beset by certain inevitabilities. Consider the following:

1. Is courage - strength of character - desirable? Then must man be reared in an environment which necessitates grappling with hardships and reacting to disappointments.
2. Is altruism - service of one's fellows - desirable? Then must life experience provide for encountering situations of social inequality.
3. Is hope - the grandeur of trust - desirable? Then human existence must constantly be confronted with insecurities and recurrent uncertainties.
4. Is faith - the supreme assertion of human thought - desirable? Then must the mind of man find itself in that troublesome predicament where it ever nows less than it can believe.
5. Is the love of truth and the willingness to go wherever it leads desirable? Then must man grow up in a world where error is present and falsehood always possible.
6. Is idealism - the approaching concept of the divine - desirable? Then must man struggle in an environment of relative goodness and beauty, surroundings stimulative of the irrepressible reach for better things.
7. Is loyalty - devotion to highest duty - desirable? Then must man carry on amid the possibilities of betrayal and desertion. The valor of devotion to duty consists in the implied danger of default.
8. Is unselfishness - the spirit of self-forgetfulness - desirable? Then must mortal man live face to face with the incessant clamoring of an inescapable self for recognition and honor. Man could not dynamically choose the divine life if there were no self-life to forsake. Man could never lay saving hold on righteousness if there were no potential evil to exalt and differentiate the good by contrast.
9. Is pleasure - the satisfaction of happiness - desirable? Then must man live in a world where the alternate of pain and the likelihood of suffering are ever-present experiential possibilities.

Seek the greater thing, and the lesser will be found therein; ask for the heavenly, and the earthly shall be included. The shadow is certain to follow the substance.
