Having seen this now several times, I find myself wondering if people are aware that it should either be &quot;dispense with once and for all the fiction that...&quot; or &quot;dispel the fiction once and for all that...&quot;. To &quot;dispel with&quot; is to use a thing to dispel, such as &quot;Let us dispel the fiction that the sky is green with this spectrograph result.&quot; (although that is still so klunky I&#x27;d never say that).
