To what degree is sense perception reliable (extended)?

First off, let's define what this class actually is:
Epistemology is the study of knowing. It deals with the nature of knowledge, how do we know things, what do we know, why we know, is what we know true, and what are the limits of knowledge.

Ways of Knowing (FLIMSIER):
  • Faith
  • Language
  • Imagination
  • Memory
  • Sense Perception
  • Intuition
  • Emotion
  • Reason
Areas of Knowledge (HH MARINE):
  • History
  • Human Sciences
  • Math
  • Arts
  • Religious Knowledge
  • Indigenous Knowledge
  • Natural Sciences
  • Ethics
We watched a picture of a face, made up of tiles. As we moved closer, the face became less and less seeable, only the tiles were left.

We also watched a video whilst doing the following task:
  1. Before watching the video: Count how many times the team in white passes the ball!
  2. How many passes did the team in white make?
  3. Did you see the moonwalking bear?
I actually find this exercise quite fun, it shows how we can not see what we are not looking for. Watch the video again and you'll see the dancing bear coming in around the 15th second. Weird, right?

We watched a video with a Charlie Chaplin "mask" where both sides were as if they were the front. I put "mask" in quotation marks because I wonder if it was something built in, or how the optical illusion worked. Here it is:



If you liked the previous exercise, here's another interesting one about the so called McGurk Effect:

  1. Look at the video.
  2. Now listen to the video without looking at it (close your eyes).
  3. Did you also hear different sounds with open and closed eyes (most people do)?
Summary of the video: The first picture showed a man making a "bah" sound, then another making a "fah" sound. The trick was that when we closed our eyes, we heard the second one also saying "bah".
My guess is they were both doing the "bah" sound and the pictures only tricked our brains into thinking of the "f" sound because his teeth touched his lips. This would be an example of how on sense can confuse another.
A very well-known example originates from the culinary world: It is a proven fact that when you can't smell something you feel as if it didn't have flavour. Think about it. Remember when you had a blocked nose (e.g. because of a common cold) - didn't you find the food flavorless? If you need further proof, you can try this little "experiment" anytime you eat, as it is safe and not really time-consuming (as long as you remember to breathe through your mouth when your nose is blocked). For even more proof, here is a picture explaining the cause of this phenomenon:
Little tip for the home chefs: there is also a strong connection between smell and memory - you might make the next dinner more enjoyable by mixing in scents that you know the eaters associate with good memories (e.g. drop a few pine needles for decoration on the food and the scent could remind the eaters of Christmas).


Final Conclusion: Some perception is reliable to a specific degree, meaning you can't trust your sense perception 100% - it might be false.


Final Questions: Does light have color? Is perception a mirror of reality or the maker of reality?
