What is Free Discussion? We answer, it is the exercise of the reasoning faculties. Without Free Discussion man cannot exist. His physical existence might indeed remain; but he could no longer be deemed a man; and would have to take a lower rank in the scale of creation.
Without investigation it is impossible to arrive at Truth; hence the utility of Free Discussion. This is never denied when science is the subject; and we have yet to learn why it should be restrained in any case; and also _how_ and _when_ any set of men became possessed of the right to restrain the exercise of the reasoning faculties of their fellow-men.
When men have not been impelled by cupidity to shackle the minds of their fellow beings, a spirit of uncharitableness has induced them to pursue the same line of conduct. Whoever has maintained an opinion contrary to theirs, has been considered as being actuated, not by mistaken, but, by dishonest motives; and has therefore been deemed a fit subject for punishment. As this work will probably be read by many professing Christians we will here give an extract from Dr. Blair's sermon on _Candor_, which will, probably, make a greater impression than any thing we could offer on that subject.
"It is one of the misfortunes of our present situation, that some of the good dispositions of human nature are apt to betray us into frailties and vices. Thus it often happens, that the laudable attachment which we contract to the country, or the church, to which we belong, or to some political denomination under which we class ourselves, both confines our affections within too narrow a sphere, and gives rise to violent prejudices against such as come under an opposite description. Not contented with being in the right ourselves, we must find all others in the wrong. We claim an exclusive possession of goodness and wisdom: and from approving warmly of those who join us, we proceed to condemn, with much acrimony, not only the principles, but the _characters_, of those from whom we differ. Hence, persons of well disposed minds are too often, through the strength of partial good affection, involved in the crime of uncharitable judgment They rashly extend to every individual the severe opinion which they have unwarrantably conceived of a whole body. This man is of a party whose principles we reckon slavish; and therefore his whole sentiments are corrupted. That man belongs to a religious sect which we are accustomed to deem bigoted; and therefore he is incapable of any generous or liberal thought Another is connected with a sect which we have been taught to account relaxed; and therefore he can have no sanctity.--Are these the judgments of candor and charity? Is true piety or virtue so very limited in its nature, as to be confined to such alone as see every thing with our eyes, and follow exactly the train of our ideas?"
