Some imputations we may mitigate by the use of other words; luxury will be softened down into generosity,
For if they refuse either to defend or to state the facts, they will be giving away their whole case. If, on the other hand, they do propose to put in a defence, they must at least, as a rule, set forth what they intend to justify. Why then not state fully facts which can be got rid of and must in fact be pointed out to make that possible?
Or again what difference is there between a proof and a statement of facts save that the latter is a proof put forward in continuous form, while a proof is a verification of the facts as put forward in the statement? Let us consider therefore whether under such circumstances the statement should not be somewhat longer and fuller than usual, since we shall require to make some preliminary remarks and to introduce certain special arguments (note that I say arguments, and not argumentation), while it will add greatly to the force of our defence if we assert not once nor twice that we shall prove what we say is true and that the significance of the facts cannot be brought out by one opening statement, bidding them wait, delay forming their opinions and hope for the best.
