I didn't like philosophy. It is too wordy even for me. The thoughts are so convoluted that they become tangled and trip over themselves.
Empiricism -- The view that experience, especially of the senses, is the only source of knowledge. (what you have experienced is what you know...if you haven't seen, smelled, tasted, touched or heard it, you don't KNOW it, and if it can't be verified by one of the senses, it is not real knowledge -- this especially applies to emotions/religion -- are they real? They cannot be verified with the senses).
Epistemiology -- philosophy that studies the nature, extent, and validity of knowledge, including foundations and presuppositions
(in other words, what exactly is knowledge? and how do we know that it is knowledge?)
Phenomenology -- reality consists of objects and events as they are perceived or understood in human consciousness and not of anything independent of human consciousness (if a tree falls in the forest and no human heard it, it didn't make a sound and may not even have happened unless someone actually comes across the tree).
Positivism -- sense perceptions are the only admissible basis of human knowledge and precise thought (see phenomenology and think about that tree again...).
Consider your philosophy class as stretching your brain in ways nurses usually do not. We nurses tend to think in straight lines, with a goal in mind (solution-oriented thinking). Philosophy is thinking for the joy of thinking, no particular place to go and you get to meander into all sorts of interesting areas...
OK, so I didn't find my philosophy class very joyful although it was an unusual little journey...
