I may be told that the Man of Science had much better pursue his studies and experiments in silence and private, and not expose himself to the persecution of bigots. The idea is slavish--disgraceful. Science has made sufficient progress in this country, and has a sufficient number of followers and admirers, to enable them by a single breath to dissipate all the bigotry in the country, or, at least, to silence all the idle clamour of the bigoted and interested about blasphemy and atheism, or any of their nonsense. Is the progress of Science to be submitted to an Excise, and are all discoveries to be treated like contraband goods, lest the trade and the tithes of the priest be injured? Shame on that man who can tacitly submit to such a system. And yet this is just what we are called upon to submit to, and threatened with punishment, and even banishment, if we murmur. I, as an humble individual, have resolved to break through those trammels, to violate all those degrading and disgraceful laws, and shall the Man of Science be silent, and see all that he values most dear, persecuted in my person, just because he will not proclaim that I am right, and that my enemies, and his enemies, are wrong? Now is the time for him to speak out--now is the time when he can do it effectually. My humble efforts have alarmed the whole of Corruption and Falsehood's hosts, and half frightened them to death, let but a few eminent and distinguished Men of Science stand forward and support me, and I have no fear of finishing well, what I have endeavoured well to begin. I aspire to nothing more than to become the humble instrument of sounding and resounding their sentiments. I am anxious to sound a loud blast in the cause of Truth, of Reason, of Nature and her laws. I will give every Man of Science an opportunity of publishing his sentiments without any direct danger to himself: I will fill the gap of persecution for him, if a victim be still necessary to satisfy the revenge of dying Priestcraft. This is an age of revolutions, and where those revolutions have not yet displayed themselves, it is not for want of the mind having been sufficiently revolutionized, but because it is kept down by a superior acting force in the shape of fixed bayonets and despotic laws. Throughout Europe the mind of the people has been long revolutionized from its wonted ignorance, and wherever it finds an opportunity, it displays itself. This march of the mind will be progressive, and it is evident that it has already begun to spread itself among the very instruments of those despots called Kings, by which they vainly hoped to have checked its course. Every march of the Russian troops into the south of Europe will but tend to enlighten them, and by and bye they will become wise enough to return and revolutionize their own country; by adopting the Representative System of Government, and by making their present Emperor what he is so well adapted for--a regimental tailor.
