He becomes foolish and ridiculous, if he dares to say that he does not know whether a difference really exists between that which is, and that which is not; for then one asks him what he did at the age of six months, at one year, two years, two weeks ago, yesterday? Whatever he replies, he will become the object of ridicule. Behold the Pyrrhonian beaten, that is to say, the one who professes to doubt everything; since a single acknowledged difference bringing him irresistibly to a certainty, and since one certainty militates against all the others, there is no further doubt; and since, doubting no further, it is only a question then of knowing what he ought, or ought not to doubt: this is the true character of the skeptic of the Socratic School. 23. _Abstain thou if ’tis evil; persevere if good._ But although one may bring the absolute skeptic to agree that a difference between good and evil can indeed exist, as he is forced to agree that one does exist between that which is and that which is not, just as I have demonstrated in my preceding Examination; would he not be right in saying, that to know in general, that good and evil can differ and consequently exist separately, does not prevent confounding them in particular; and that he can doubt that man may be able to make the distinction, until one may have proved to him that not alone their knowledge, but that some sort of knowledge is possible? Assuredly, this is pushing doubt very far. One could dispense with replying to this, since the skeptic already interrogated concerning the difference existing between what is and what is not has been forced to admit it and to acquire thus some sort of knowledge of being; but let us forget this, in order to examine why the savants of Germany have inadequately removed a difficulty which they have imposed upon themselves.
