The following is a rather disjointed jumble of random thoughts on silence.
Used in Wisdom
I have seen silenced used with wisdom in such a way as to enlighten or simply to not engage in base folderal.
Used in Uncertainty
Silence can avoid committing to something when one isn't sure
Used as a Vote
A silent response to a claim, statement on in place of another expected response is a very safe way to say fuck you.
Used as a Shield
I have seen silence used to hide from consequences basically a silent lie.
Used as a Weapon
I've seen silence used to harm as information is withheld with malice.
Used in Fear
I have seen fearful people use silence when they should speak. This ranges from a petty argument to what is discussed in that poignant work that condemns inappropriate silence, First They Came by Pastor Martin Niemöller (1892–1984).
Used for the Ego
I have those that fool themselves into thinking silence is source of pride when really it is being used for social manipulation and the one-sided gathering of information.
Used in the Present
Unsure if I should utter a warning or not as I know not whether warning is warranted or inappropriate, helpful or harmful, a guide post or a inappropriate road block or based on my own insecurities or on my own past-spawned baseless fears. I practice silence now. This is the silence of the my personal version of the Queen of Wands.
