Descartes writes, $"$if I consider closely, as I yesterday examined the idea of wax, I find there is little I perceive clearly and distinctly. Magnitude, extensions in length, breadth, or depth I do so perceive, also substance, duration and number. As to other things such as light, colors, sounds, scents, smells, tastes, heat, cold, they are thought with so much obscurity and confusion that I do not know if they are true or false" he is articulating:

His annoyance with the wax

the truth of mathematical physics

the truth and certitude of ordinary experience

none of the above
