Humans generally can comprehend cause-and-effect relationships within simple systems (as they can with robots). Yet they themselves provide such incomprehensible action that humans will often resort to some idea like Free-Will in order to find a cause.
Why should man fear the darkness, the black? It is light that stole away from us nine months of safety we held in shadow. It is light that illuminates fears its absence graciously denies. It is in darkness that we find rest and solitude and new strength. It is in darkness, a mere emptiness, that we quiet the mind.
No one should be afraid of darkness for cause of death. Black and darkness do not accompany the end; there exists no color in death for we do not exist to see one.
A specific sentence may have a variety of meanings depending on the way it is pronounced and the context of the situation. Because of this, a speaker must trust that the audience correctly identifies intended meaning. Human nature provides a natural instinct for deciphering the many subtleties of language, complexities that hide more meaning than evident at face value. Thus, unless hindered by some cultural difference, this trust is justified and humans generally can communicate ideas successfully.
We veil meaning within subtlety mainly because it saves time and because saying some statements out-right would be considered brash and offensive. Conversation is dealt with like a game where each player must fight for a turn to speak. The objective is to be right, even if you are wrong. In order to win, people say what they feel and let emotion or doctrine or convention make a response, not logic and rationality. Here then the words become less ours. One does not think of sentences and with awareness speak them. The ideology does.
Those who leave the womb at birth
and those who enter their source at death,
of these; three out of ten celebrate life,
three out of ten celebrate death,
and three out of ten simply go from life to death.
What is the reason for this?
Because they are afraid of dying,
therefore they can not live.
-Tao Te Ching 50
When people see things as beautiful,
ugliness is created.
When people see thins as good,
evil is created.
Being and non-being produce each other.
Difficult and easy complement each other
Long and short define each other.
Fore and aft follow each other.
