After a point, 100% will agree (anybody not agreeing that an obvious heap of say 100kg of sand is not a heap but just grains, can be discarded as a madman).<p>But still the exact point can&#x27;t be specified, we only know when it&#x27;s over-surpassed.<p>It&#x27;s like in the famous trial, when they asked someone to specify is a film is &quot;porn&quot; or &quot;erotic art&quot;, and he said:<p>&quot;I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description [&quot;hard-core pornography&quot;], and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the motion picture involved in this case is not that.&quot;
