On lower lev­els of mu­sic our tools of cog­ni­tion, feel­ing and un­der­stand­ing, are enli­vened only to a small de­gree. This re­sults in a cor­re­spond­ingly in­fe­rior mu­si­cal knowl­edge which in ac­cor­dance with its low level of en­ergy is as­so­ci­ated with only a weak doubt.
The deeper, how­ever, we fathom the depth of the mu­si­cal mean­ing, and the more our feel­ing and un­der­stand­ing ac­ti­vate their in­her­ent pow­ers of cog­ni­tion dur­ing our proc­ess of gain­ing knowl­edge in mu­sic, the more these tools of cog­ni­tion be­gin to clash in our in­tel­lect-space if the ab­so­lu­te sound-sub­stance is not enli­vened, or not enli­vened pro­por­tionately to the depth of the proc­ess of cog­ni­tion like two rivers that flow against each other, the one per­ma­nently pro­duc­ing heat, the other per­ma­nently pro­duc­ing cold.

Con­se­quently, the phe­nome­non of doubt has dif­fer­ent impact in dif­fer­ent force-fields of mu­sic.
Thus, a lis­tener but a would-be com­poser as well may vir­tu­ally exhaust him­self from in­ner doubts if his mind, his in­tel­lect, his feel­ing and un­der­stand­ing, and his sense of hear­ing are not enli­vened col­lec­tively on the level of the ab­so­lu­te sound-sub­stance.

In such a case mu­sic may ac­tu­ally have a demor­aliz­ing ef­fect on the lis­tener and may truly frustrate him.
Van­dal­ism in the wake of beat and pop con­certs is the strik­ing evi­dence of such symp­toms of frus­tra­tion.

Far worse, how­ever, is the ef­fect which the frus­tra­tion has that re­sults from the con­sump­tion of shal­low decrepit en­ter­tain­ment mu­sic it leads to giv­ing up the quest for the mean­ing of our life, i.e. to giv­ing up the higher des­ti­na­tion of our hu­man life.
