Stating an unproven negative holds the same value to me as stating an unproven positive. That&#x27;s a fact and that&#x27;s exactly what I said.<p>Stating an unproven negative as if it were a fact is also not the best scientific approach.<p>(Also, saying something like &quot;the mind has no affect on the body&quot; is a positive statement of fact. Quibbling about the word &quot;no&quot; or &quot;not&quot; is just semantics IMO.)
