But considering, that amongst all those who formerly have sought the Truth in Learning, none but the Mathematicians only could finde any demonstrations, that's to say, any certain and evident reasons. I doubted not, but that it was by the same that they have examin'd; although I did hope for no other profit, but only that they would accustome my Minde to nourish it self with Truths, and not content it self with false Reasons.
eta gogoan harturik gaur egun arte egia zientzietan ikertu duten guztien artetik matematikariek bakarrik lortu ahal izan dutela frogapen batzuk-hau da, egiazko eta ebidenteak diren arrazoi batzuk-, ez nuen zalantzarik eurek aztertu dituzten gauza horiexetatik hasi behar zela, nahiz eta hortik baliagarritasun bakarra baino ez nuen espero, hots, nire adimena ohituko zela egiez elikatzera eta arrazoi faltsuekin ez konformatzera.
