"The fact that this is probably,in any full sense, imossible ,should not deter us from try it on."
Please clarify this for me ? If it is "in any full sense" impossible , why he says " probably" ? what does "in any full sense" mean here?
The fact that this is impossible and does not make sense should not deter us from trying.
Is that close to what you are saying?
Hope this helps,
