Suppose it should be asserted that sound is the conflict between two bodies, the statement would in my opinion be erroneous. For sound is not the actual conflict, but a result of the conflict. The error is, however, of small importance: for the sense is clear, whatever the expression. But this trivial mistake has given rise to a very serious error in the minds of those who have not understood what was meant: for on reading that the essential basis was the first conflict, they immediately concluded that the basis was always to be taken from the first question, which is a grave mistake.
For every question has its basis, since every question is based on assertion by one party and denial by another. But there are some questions which form an essential part of causes, and it is on these that we have to express an opinion; while others are introduced from without and are, strictly speaking, irrelevant, although they may contribute something of a subsidiary nature to the general contention. It is for this reason that there are said to be several questions in one matter of dispute.
Of these questions it is often the most trivial which occupies the first place. For it is a frequent artifice to drop those points in which we place least confidence, as soon as we have dealt with them; sometimes we make a free gift of them to our
A simple cause, however, although it may be defended in various ways, cannot have more than one point on which a decision has to be given, and consequently the basis of the cause will be that point which the orator sees to be the most important for him to make and on which the judge sees that he must fix all his attention. For it is on this that the cause will stand or fall. On the other hand questions may have more bases than one. [*](See § 21.)
A brief example will show what I mean. When the accused says
Admitting that I did it, I was right to do it,he makes the basis one of quality; but when he adds
but I did not do it,he introduces an element of conjecture. [*]( See § 30 aqq. ) But denial of the facts is always the stronger line of defence, and therefore I conceive the basis to reside in that which I should say, if I were confined to one single line of argument.
