Tips for Writing a personal Narrative

How did things get this way? Can something people have spent thousands of years studying really be a waste of time? Those are interesting questions. In fact, some of the most interesting questions you can ask about philosophy. The most valuable way to approach the current philosophical tradition may be neither to get lost in pointless speculations like berkeley, nor to shut them down like wittgenstein, but to study it as an example of reason gone wrong. History western philosophy really begins with Socrates, Plato, and Aristotle.

Everyday words are inherently imprecise. They work well enough in everyday life that you don't notice. Words seem to work, just as Newtonian physics seems. But you can always make them break if you push them far enough. I would say that this has been, unfortunately for philosophy, the central fact of philosophy. Most philosophical debates are not merely afflicted by but driven by confusions over words. Do we have free will? Depends what resume you mean by "free." do abstract ideas exist? Depends what you mean by "exist." Wittgenstein is popularly credited with the idea that most philosophical controversies are due to confusions over language. I'm not sure how much credit to give him. I suspect a lot of people realized this, but reacted simply by not studying philosophy, rather than becoming philosophy professors.

But there's no central, indivisible thing that your identity goes with. You could conceivably lose half your brain and live. Which means your brain could conceivably be split into two halves and each transplanted into different bodies. Imagine waking up after such an operation. You have to imagine being two people. The real lesson here is that the concepts we use in everyday life are fuzzy, and break down if pushed too hard. Even a short concept as dear to us. It took me a while to grasp this, but when I did it was fairly sudden, like someone in the nineteenth century grasping evolution and realizing the story of creation they'd been told as a child was all wrong. 2 outside of math there's a limit to how far you can push words; in fact, it would not be a bad definition of math to call it the study of terms that have precise meanings.

I don't know if I thesis learned anything from them. 1, it does seem to me very important to be able to flip ideas around in one's head: to see when two ideas don't fully cover the space of possibilities, or when one idea is the same as another but with a couple thesis things changed. But did studying logic teach me the importance of thinking this way, or make me any better at it? There are things i know I learned from studying philosophy. The most dramatic I learned immediately, in the first semester of freshman year, in a class taught by sydney shoemaker. I learned that I don't exist. I am (and you are) a collection of cells that lurches around driven by various forces, and calls itself.

I do at least know now why i didn't. Philosophy doesn't really have a subject matter in the way math or history or most other university subjects. There is no core of knowledge one must master. The closest you come to that is a knowledge of what various individual philosophers have said about different topics over the years. Few were sufficiently correct that people have forgotten who discovered what they discovered. Formal logic has some subject matter. I took several classes in logic.

Anything so admired and so difficult to read must have something in it, if one could only figure out what. Twenty-six years later, i still don't understand Berkeley. I have a nice edition of his collected works. Will i ever read it? The difference between then and now is that now i understand why.

Berkeley is probably not worth trying kierkegaard to understand. I think i see now what went wrong with philosophy, and how we might fix. Words, i did end up being a philosophy major for most of college. It didn't work out as I'd hoped. I didn't learn any magical truths compared to which everything else was mere domain knowledge.

I would be learning what was really what. I'd tried to read a few philosophy books. Not recent ones; you wouldn't find those in our high school library. But I tried to read Plato and Aristotle. I doubt I believed i understood them, but they sounded like they were talking about something important.

I assumed I'd learn what in college. The summer before senior year I took some college classes. I learned a lot in the calculus class, but I didn't learn much in Philosophy 101. And yet my plan to study philosophy remained intact. It was my fault I hadn't learned anything. I hadn't read the books we were assigned carefully enough. Principles of Human Knowledge another shot in college.

See also edit references edit retrieved from filsafat " p? September 2007, in high school I decided I was going to study philosophy in college. I had several motives, some more honorable than others. One of the less honorable was to shock people. College was regarded as job training where i grew up, so studying philosophy seemed an impressively impractical thing. Sort of like slashing holes in your clothes or putting a safety pin through your ear, which were other forms of impressive impracticality then just coming into fashion. But I had some more honest motives as well. I thought studying philosophy would be a shortcut straight to wisdom. All the people majoring in other things would just end up with a bunch of domain knowledge.
