In every respect the burthen is hard on those who attack an almost universal opinion. They must be very fortunate as well as unusually capable if they obtain a hearing at all. They have more difficulty in obtaining a trial, than any other litigants have in getting a verdict. If they do extort a hearing, they are subjected to a set of logical requirements totally different from those exacted from other people. In all other cases, the burthen of proof is supposed to lie with the affirmative. If a person is charged with a murder, it rests with those who accuse him to give proof of his guilt, not with himself to prove his innocence. If there is a difference of opinion about the reality of any alleged historical event, in which the feelings of men in general are not much interested, as the Siege of Troy for example, those who maintain that the event took place are expected to produce their proofs, before those who take the other side can be required to say anything; and at no time are these required to do more than show that the evidence produced by the others is of no value. Again, in practical matters, the burthen of proof is supposed to be with those who are against liberty; who contend for any restriction or prohibition; either any limitation of the general freedom of human action, or any disqualification or disparity of privilege affecting one person or kind of persons, as compared with others. The _à priori_ presumption is in favour of freedom and impartiality. It is held that there should be no restraint not required by the general good, and that the law should be no respecter of persons, but should treat all alike, save where dissimilarity of treatment is required by positive reasons, either of justice or of policy. But of none of these rules of evidence will the benefit be allowed to those who maintain the opinion I profess. It is useless for me to say that those who maintain the doctrine that men have a right to command and women are under an obligation to obey, or that men are fit for government and women unfit, are on the affirmative side of the question, and that they are bound to show positive evidence for the assertions, or submit to their rejection. It is equally unavailing for me to say that those who deny to women any freedom or privilege rightly allowed to men, having the double presumption against them that they are opposing freedom and recommending partiality, must be held to the strictest proof of their case, and unless their success be such as to exclude all doubt, the judgment ought to go against them. These would be thought good pleas in any common case; but they will not be thought so in this instance. Before I could hope to make any impression, I should be expected not only to answer all that has ever been said by those who take the other side of the question, but to imagine all that could be said by them--to find them in reasons, as well as answer all I find: and
