Man by necessity acts across time. In initiating action man communicates – at the very least his passing preoccupation. Man by volition explicitly communicates to his fellow. In initiating explicit communication man implies – at the very least his apparent intention.
Action communicates; communication implies.
How one acts is always in an ultimate sense communicated. Why one acts is always in an ultimate sense implied.
Assuming he does not think he lacks even an infinitesimal degree of free will – perhaps an impossible thing to genuinely believe - man likely acts in an orderly manner insofar as he does not perceive his actions to be initiated, for all man’s actions are continuous – and only perceived to be discrete.
Assuming he does not believe he is entirely incapable of explicit communication – perhaps an impossible thing to actually think – man likely acts in an orderly manner insofar as he does not perceive his communication to be explicit, for all man’s communications are implicit – and only perceived to be explicit.
To communicate only by the implied meaning of action is an unintended consequence of acting in an entirely orderly manner, which is impossible for a mere man, since to do so requires the capacity to satisfy one's desires entirely or at least to satisfy his desires regardless of the actions of others, but he that could do either would not only eschew communication deliberately but be immortal and, therefore, incapable of communicating in the human sense at all.
How the man of Eden acts is exactly why he acts, for his only preoccupation is exactly his only intention: his very being.
Notwithstanding appearances to the contrary, how man lives is ultimately why he does; and so, the why and how of all human action are essentially synonymous. The mortal must strive to recognize that great truth; insofar as he does, he likely will act in an orderly manner and, as a consequence, explicitly communicate less. To communicate only by implication is to align with a divine mandate of social order: discretion.
