What should ye do then? should ye suppress all this flowery crop of knowledge and new light sprung up and yet springing daily in this city? should ye set an oligarchy of twenty engrossers over it, to bring a famine upon our minds again, when we shall know nothing but what is measured to us by their bushel? Believe it, Lords and Commons, they who counsel ye to such a suppressing do as good as bid ye suppress yourselves; and I will soon show how. If it be desired to know the immediate cause of all this free writing and free speaking, there can not be assigned a truer than your own mild and free and humane government. It is the liberty, Lords and Commons, which your own valorous and happy counsels have purchased us, liberty which is the nurse of all great wits; this is that which hath rarefied and enlightened our spirits like the influence of heaven; this is that which hath enfranchised, enlarged and lifted up our apprehensions degrees above themselves.
Ye can not make us now less capable, less knowing, less eagerly pursuing of the truth, unless ye first make yourselves, that made us so, less the lovers, less the founders of our true liberty. We can grow ignorant again, brutish, formal and slavish, as ye found us; but you then must first become that which ye can not be, oppressive, arbitrary and tyrannous, as they were from whom ye have freed us. That our hearts are now more capacious, our thoughts more erected to the search and expectation of greatest and exactest things, is the issue of your own virtue propagated in us; ye can not suppress that, unless ye reinforce an abrogated and merciless law, that fathers may dispatch at will their own children. And who shall then stick closest to ye, and excite others? not he who takes up arms for coat and conduct, and his four nobles of Danegelt. Altho I dispraise not the defense of just immunities, yet love my peace better, if that were all. Give me the liberty to know, to utter, and to argue freely according to conscience, above all liberties.
I can not praise a fugitive and cloistered virtue, unexercised and unbreathed, that never sallies out and sees her adversary, but slinks out of the race, where that immortal garland is to be run for, not without dust and heat. Assuredly we bring not innocence into the world, we bring impurity much rather; that which purifies us is trial, and trial is by what is contrary. That virtue therefore which is but a youngling in the contemplation of evil, and knows not the utmost that vice promises to her followers, and rejects it, is but a blank virtue, not a pure; her whiteness is but an excremental whiteness. Which was the reason why our sage and serious poet Spenser, whom I dare be known to think a better teacher than Scotus or Aquinas, describing true temperance under the person of Guion, brings him in with his palmer through the cave of Mammon, and the bower of earthly bliss, that he might see and know, and yet abstain. Since therefore the knowledge and survey of vice is in this world so necessary to the constituting of human virtue, and the scanning of error to the confirmation of truth, how can we more safely, and with less danger, scout into the regions of sin and falsity than by reading all manner of tractates and hearing all manner of reason? And this is the benefit which may be had of books promiscuously read.
