These and the like actions of corporeal Nature or natural Matter you may find more at large described in my afore-mentioned Book of _Philosophical Opinions_, and more clearly repeated and explained in this present. 'Tis true, the way of arguing I use, is common, but the Principles, Heads and Grounds of my Opinions are my own, not borrowed or stolen in the least from any; and the first time I divulged them, was in the year 1653: since which time I have reviewed, reformed and reprinted them twice; for at first, as my Conceptions were new and my own, so my Judgment was young, and my Experience little, so that I had not so much knowledge as to declare them artificially and methodically; for as I mentioned before, I was always unapt to learn by the Rules of Art. But although they may be defective for want of Terms of Art, and artificial expressions, yet I am sure they are not defective for want of Sense and Reason: And if any one can bring more Sense and Reason to disprove these my opinions, I shall not repine or grieve, but either acknowledge my error, if I find my self in any, or defend them as rationally as I can, if it be but done justly and honestly, without deceit, spight, or malice; for I cannot chuse but acquaint you, _Noble Readers_, I have been informed, that if I should be answered in my Writings, it would be done rather under the name and cover of a Woman, then of a Man, the reason is, because no man dare or will set his name to the contradiction of a Lady; and to confirm you the better herein, there has one Chapter of my Book called _The Worlds Olio_, treating of a Monastical Life, been answer'd already in a little Pamphlet, under the name of a woman, although she did little towards it; wherefore it being a Hermaphroditical Book, I judged it not worthy taking notice of. The like shall I do to any other that will answer this present work of mine, or contradict my opinions indirectly with fraud and deceit. But I cannot conceive why it should be a disgrace to any man to maintain his own or others opinions against a woman, so it be done with respect and civility; but to become a cheat by dissembling, and quit the Breeches for a Petticoat, meerly out of spight and malice, is base, and not fit for the honour of a man, or the masculine sex. Besides, it will easily be known; for a Philosopher or Philosopheress is not produced on a sudden. Wherefore, although I do not care, nor fear contradiction, yet I desire it may be done without fraud or deceit, spight and malice; and then I shall be ready to defend my opinions the best I can, whilest I live, and after I am dead, I hope those that are just and honorable will also defend me from all sophistry, malice, spight and envy, for which Heaven will bless them. In the mean time, _Worthy Readers_, I should rejoyce to see that my Works are acceptable to you, for if you be not partial, you will easily pardon those faults you find, when you
