Chapter 4 talks about our sensations and perceptions, or in other words, "how we sense and conceptualize the world. In this chapter, the book addresses talks about our visual system, our auditory system, our sensual senses (taste and smell), and our body senses (touch, body position and balance) and explains how they work. One thing that stood out as super interesting, for me, was when this chapter addressed extrasensory perception (ESP). I've always wondered whether or not stories of ESP were true. Additionally, I enjoyed this chapter because it reminded me of the importance of our senses, and how much we use them each day.
