 The method of not erring is sought by all the world. The logicians profess to guide to it, the geometricians alone attain it, and apart from their science, and the imitations of it, there are no true demonstrations. The whole art is included in the simple precepts that we have given; they alone are sufficient, they alone afford proofs; all other rules are useless or injurious. This I know by long experience of all kinds of books and persons.

And on this point I pass the same judgment as those who say that geometricians give them nothing new by these rules, because they possessed them in reality, but confounded with a multitude of others, either useless or false, from which they could not discriminate them, as those who seeking a diamond of great price amidst a number of false ones, but from which they know not how to distinguish it, should boast, in holding them all together, of possessing the true one equally with him who without pausing at this mass of rubbish lays his hand upon the costly stone which they are seeking and for which they do not throw away the rest.

The defect of false reasoning is a malady which is cured by these two remedies. Another has been compounded of an infinity of useless herbs in which the good are enveloped and in which they remain without effect through the ill qualities of the compound.

To discover all the sophistries and equivocations of captious reasonings, they have invented barbarous names that astonish those who hear them; and whilst we can only unravel all the tangles of this perplexing knot by drawing out one of the ends in the way proposed by geometricians, they have indicated a strange number of others in which the former are found included without knowing which is the best.

And thus, in showing us a number of paths which they say conduct us whither we tend, although there are but two that lead to it, it is necessary to know how to mark them in particular. It will be pretended that geometry which indicates them with certainty gives only what had already been given by others, because they gave in fact the same thing and more, without heeding that this boon lost its value by abundance, and was diminished by adding to it.

Nothing is more common than good things: the point in
