Socrates said very well, life is not constant.
In my studies and readings in search of answers, I found this description about our existence.
The entire life of the evolutionary creature is besieged by certain inevitability.
1. Courage — is strength of character desirable? So, man should be raised in an environment that requires coping with difficulties and a reaction to disappointments.
2. Is altruism — is service to others desirable? Then, the experience of life should provide you with situations of social inequality.
3. Is hope — is the greatness of trust desirable? So human existence must constantly confront renewed insecurity and uncertainty.
4. Is faith— is the supreme affirmation of human thought desirable? So the human mind must be faced with great difficulties, in which it always knows less than it can believe.
5. Is the love of truth and the willingness to go wherever that love leads desirable? So man must grow up in a world where error is present and falsehood is always possible.
6. Is idealism — a concept very close to the divine desirable? So man must toil around an environment of relative goodness and beauty, which stimulate the unrestrained search for better things.
7. Is loyalty — devotion to higher duty desirable? So the man must keep going forward, though surrounded by possibilities of betrayal and desertion. The value of devotion to duty stems from the implicit danger of failure.
8. Is detachment — is the spirit of self-forgetfulness desirable? So mortal man must live face to face with the incessant cry of an inescapable ego that requires recognition and honor. Man could not choose divine life in a dynamic way if there was no life of the ego to which to renounce. Man could never hold on to salvation, in righteousness, if there was no potential evil exalting and differentiating good by contrast.
9. Pleasure— is the satisfaction of happiness desirable? So man must live in a world where the alternative of pain and the probability of suffering are ever-present experience possibilities.
