"Ordinarily pleasure and pain are regarded as different from sensations"

Ernst Mach's quote suggests that pleasure and discomfort are not necessarily the same as feelings. This suggests that satisfaction and discomfort are not simply physical experiences, but rather, they are more complex psychological and psychological experiences. Enjoyment and pain are often associated with physical experiences, however they are not always the exact same thing. Pleasure and discomfort can be caused by a range of aspects, such as memories, expectations, and beliefs. For instance, an individual may experience satisfaction when they consume a preferred food, but the physical experience of eating the food may not be satisfying. Similarly, an individual may experience pain when they are injured, however the physical experience of the injury might not hurt. For that reason, enjoyment and pain are more than just physical sensations, and they need to be considered as distinct experiences.
