Can you answer my question, in a few paragraphs how would you introduce someone to Philosophy?
OK, this may take some time...
Philosophy can be abstract and theoretical. Humans do things for reasons, we desire certain things and believe that acting in certain ways will get us those things. Values and concepts are the building blocks of desires and beliefs. Humans also reflect on and criticise the reasons we do things. We constantly question whether or not we have good reasons for whatever we are doing and for whatever we are believing. Having the capacity to reflect on one's reason is another part of being human.
Everyone has this sort of capacity, this ability to reflect on basic concepts and values. It is the love of this activity which is philologically what philosophy is: the love of reason. If you worry about whether there is a God or not, what the difference between the future and the past is, why we can't turn around in time as we can in space, whether one is a brain in a vat in another's experiment, whether other humans have minds or just you, how you would know if blue things looked to you just like green things looked to everyone else, how one can be 'free' if every physical event has a physical cause, or why it was wrong to lie and cheat. These are philosophical conundrums and if you worry about them you may be inclined towards this great and ancient tradition of focusing on the minute details of these various problems logically and reasonably.
Philosophy means thinking as hard and as clearly as one can about some of the most interesting and enduring problems that human minds have ever encountered. Some of these problems have been discussed since ancient times. Whether an act is right or wrong has been discussed by both Plato and David Hume, and very many people in between. To read philosophy well one must read slowly and aggressively. Good philosophers develop arguments and theories of some intricacy; arguments that are designed to convince the reader of the author's position on important issues.
Philosophy is also inevitably technical. The philosopher constructs arguments, theories, positions or criticisms in an attempt to persuade his or her most intelligent and perceptive opponents. To understand these sorts of arguments best one must engage with them from the most intelligent and perceptive perspective possible. To read philosophy aggressively, one should always imagine oneself in dialogue with the philosopher. I'll give an example in reading Descartes
First Meditation.
Descartes said:
Today, then having rid myself of worries and having arranged for some peace and quiet, I withdraw alone, free at last earnestly and wholeheartedly to overthrow all my beliefs.
To do this, I do not need to show each of my beliefs to be false; I may never be able to do that. But since reason now convinces me that I ought to with-hold my assent just as carefully from what is not obviously certain and indubitable as from what is obviously false, I can justify the rejection of all my beliefs if I can find some ground for doubt in each. And, to do this, I need not take on the endless task of running through my beliefs one by one: since a building collapses when its foundation is cut out from under it. I will go straight to the principles on which all my former beliefs rested.
One may engage for example with the second paragraph:
Descartes: To do this...
Reader: To do what? Overthrow all your beliefs. And what does that mean? Every single one of them? This does seem like an odd sort of endeavour...
Descartes: I do not need to show each of my beliefs to be false; I may never be able to do that...
Reader: OK so not every belief, yet why the desire to do so?
Descartes: But, since reason convinces me . . .
Reader: Reason? I wonder what exactly you may mean by that? I tend to use the word more as a verb than a noun. The dictionary definition would suggest something more as in a statement offered in explanation, connoting motive or sanity or intelligence. Are you saying your intelligence convinces you that you should be a great deal more cautious about what you believe? There may be more to this than that though since you seem to come from a tradition of "rationalism"...
Descartes: ... That I ought to with-hold my assent just as carefully from what is not obviously certain and indubitable as from what is obviously false; I can justify the rejection of all my beliefs if I can find some ground for doubt in each.
Reader: Let's get this straight: You said you would overthrow your beliefs just before then you said that to do this you don't need to show they are false. So with-holding assent may be something of an inbetween position... Yet, is this the case in reality to specific epistemological statements? If I don't believe that 1+1=2 then don't I automatically believe that it is not the case that 1+1=2? This may be true for rather simplistic notions however if I engage with larger mathematical problems I may be inclined to with-hold asset, until I add up 211435 + 2345 I'm not inclined to say one way or the other what the answer may be... What does the contrast between certainty and indubitable matters mean? Are you saying that what you are going to do is the same for everything, except that which is obviously certain or undoubtable?
Descartes: I can justify the rejection of all my beliefs if I can find some ground for doubt in each...
Reader: Well, not believing something on the grounds of being unsure or that something sounds weird, I guess that makes sense. But "ground for doubt" seems more technical... a basis for belief seems to me to be an exhausting project to try to refute.. This book is so short how can you go through each and every one of your beliefs?
Descartes: And, to do this, I need not take on the endless task of running through my beliefs one by one...
Reader: Thank heavens!
Descartes: ... Since a building collapses when its foundation is cut out from under it, I will go straight to the principles on which my former beliefs rested.
Reader: Is this an argument from metaphor? This seems a bit dubious. Are the assumptions underlying the appropriateness of this metaphor? You seem to think beliefs are a form of structure with foundations, so the foundation is a principle (or group of principles). I suppose beliefs depend in some way on certain principles... So you are going to isolate certain beliefs, on which the rest depend, and if you have grounds for doubt you will quit believing them, in the sense that you will with-hold assent? In doing so you will have ground for doubting all other beliefs which depend on this dubious principle? It seems like this should take longer than 50 pages but we shall see...
