The chapter which Mr. Mill devotes to this subject--the liberty of discussion and publication--is thoroughly exhaustive in its character. It presents the question in almost every light in which it is desirable to see it, and successfully meets every objection which can be made to his doctrine. For the first time, a logical and philosophical exposition of the great principles of liberty is presented to the world, and that too in a most readable and attractive form. The work is calculated to do immense good. It places liberty on a rational foundation, and dispels every doubt which might have been entertained by the timid, as to the safety and propriety of permitting free discussion on those points of belief which are too often held to be beyond the domain of investigation and argument. We do not pretend, here, to give anything like a synopsis of the grounds assumed, and the reasonings adopted by the author. A full and correct idea of these can only be obtained from the book itself. But before leaving this part of the work, we cannot forbear quoting a passage on this subject from an essay by Henry Thomas Buckle. Even at the risk of prolonging this article beyond its proper limits, we quote at some length, on account of the vast interest of the topic and the different notions which too generally prevail as to the propriety of its discussion: 'If they who deny the immortality of the soul, could, without the least opprobrium, state in the boldest manner all their objections, the advocates of the doctrine would be obliged to reconsider their own position and to abandon its untenable points. By this means, that which I revere, and an overwhelming majority of us revere, as a glorious truth, would be immensely strengthened. It would be strengthened by being deprived of those sophistical arguments which are commonly urged in its favor, and which give to its enemies an incalculable advantage. It would moreover be strengthened by that feeling of security which men have in their own convictions, when they know that everything is said against them which can be said, and that their opponents have a fair and liberal hearing. This begets a magnanimity and a rational confidence which cannot otherwise be obtained. But, such results can never happen while we are so timid, or so dishonest, as to impute improper motives to those who assail our religious opinions. We may rely upon it that as long as we look upon an atheistical writer as a moral offender, or even as long as we glance at him with suspicion, atheism will remain a standing and permanent danger, because, skulking in hidden corners, it will use stratagems which their secrecy will prevent us from baffling; it will practise artifices to which the persecuted are forced to resort; it will number its concealed proselytes to an extent of which only they who have studied this painful subject are
