How uncertain and imperfect would our ideas be of an ellipsis, if we had no other idea of it, but some few of its properties? Whereas, having in our plain idea the WHOLE essence of that figure, we from thence discover those properties, and demonstratively see how they flow, and are inseparable from it.
Eta hau berdin litzateke irudi matematikoei dagokienez ere, baldin ideia konplexuak beste irudi batzuekin erlazionatuz baino erdietsi ezin bagenitu. Zein ziurgabeak eta inperfektuak ez ote lirateke elipseari buruz, adibidez, guk egindako ideiak, hartaz geneukakeen ideia osoa haren propietate batzuetara mugatuko balitz?
