On the one hand, no. Some insights carry their own validation it seems. For example when I first heard that “slacks” were the opposite of “tights” I did not need anyone else to tell me this was true. The two words just fell into place and formed a new configuration — opposite kinds of leg gear, depending upon degree of looseness. The whole human race could array against me in battle regalia, waving flags that said “SLACKS AND PANTS ARE NOT OPPOSITES — THAT IS JUST A CO-INCIDENCE” and I would stand firm. And indeed, this makes sense, because if one person cannot find confidence in himself then how can he give it to others? There needs to be a gold standard, otherwise we are just exchanging worthless paper, backed up by nothing. Doesn’t there?
But on the other hand, yes. If my insight falls on deaf ears from those I care about my confidence seems to wither, or harden into a defensive posture, held more tightly in defiance against the incomprehension of my fellows. If it is greeted by understanding it grows; if not I start to wonder what I even mean by it. And in fact, in the case of money there need not be a gold standard; as long as we accept each other’s currency it does not need to be backed up by anything. Just as there is no mythical store of gold we can all exchange our dollars for, there is no mythical store of truth we can all exchange our sentences and beliefs for. It is enough to keep things going if I can convince others.
And yet…what good is it to convince others if my beliefs and insights don’t back me up in the final extremity when I die alone? Or, you could ask, what need do I have of convincing and being convinced then, or believing, or talking, or having experiences, or insights even?
But at that moment I have to ask — Who are these others anyway? Are they anyone else than different configurations of this same naked self, whom the pants of insights an opinions and beliefs both conceal and reveal, hanging sometimes tightly, and sometimes slack.
