For which (not knowing how the ideas of our minds are framed, of what materials they are made, whence they have their light, and how they come to make their appearances) I can give no other reason but experience: and I would have any one try, whether he can keep one unvaried single idea in his mind, without any other, for any considerable time together.
Horregatik (ez dakidanez nola eratzen diren gure gogameneko ideiak, ez nolako materialez eginak diren, ez nondik hartzen duten beren argia, ez nola lortzen duten agertzea), esperientzia beste arrazoirik ezin dut eman; eta gustatuko litzaidake norbait saiatzea ikusten ea eduki ahal duen gogamenean ideia bakun bat aldatu gabe, harekin batera nahiko luzaro beste ideiarik eduki gabe.
