"When we consider the positive evil caused to the disqualified half of the human race by their disqualification — first in the loss of the most inspiriting and elevating kind of personal enjoyment, and next in the weariness, disappointment, and profound dissatisfaction with life, which are so often the substitute for it; one feels that among all the lessons which men require for carrying on the struggle against the inevitable imperfections of their lot on earth, there is no lesson which they more need, than not to add to the evils which nature inflicts, by their jealous and prejudiced restrictions on one another. Their vain fears only substitute other and worse evils for those which they are idly apprehensive of: while every restraint on the freedom of conduct of any of their human fellow-creatures (otherwise than by making them responsible for any evil actually caused by it), dries up pro tanto the principal fountain of human happiness, and leaves the species less rich, to an inappreciable degree, in all that makes life valuable to the individual human being."
