Figure 1.6 Look at this drawing first, then close your eyes and turn the page, so you are looking at the same place on the page directly under this one. Then open and shut your eyes rapidly. ( Adapted Bugelski & D. Alampay, 1961.)

Figure 1.9 Did you see a “rat” or a “man”? Looking at the more ratlike picture in Figure 1.11 increased the changes that you would see this one as a rat. But if you had first seen the man version (Figure 1.8), you would have been more likely to perceive this figure as a man. (Adapted Bugelski & D. Alampay, 1961.)

Perception and Philosophy the Perceptual World and the Physical World Is perception veridical? Does world we perceive correspond to the physical world that‘s out there? Can we trust our senses to tell the truth? Late 17th, early 18th century: skepticism John Locke: arm in water basin (subjectivity of perceived qualities of the world) Primary qualities : real qualities actually present in the object (e.g. number, motion, shape…) Secondary qualities : qualities that result from an object‘s power to produce a sensation in us and depend on our state of mind (e.g. warmth, color taste, sound, smell…)

Perception and Philosophy the Perceptual World and the Physical World Is perception veridical? Does world we perceive correspond to the physical world that‘s out there? Can we trust our senses to tell the truth? Late 17th, early 18th century: skepticism David Hume: all sense experiences are subjective and unreliable; perception cannot be understood As to those impressions that arise from the senses, their ultimate cause is, in my opinion, perfectly inexplicable by human reason, and it will always be impossible to decide whether they arise from the object, or are produced by the creative power of the mind, or are derived from the author of our being“.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
