It is possible to have a view in which a grammar has some description, and a bit of prescription. If someone speaking English used only "sentences" without verbs, then a bit of prescription might be in order, and the response that "grammar is descriptive not prescriptive" would or should fall on very deaf ears. For the language at the moment does have verbs. And the same is true if someone confuses "infer" and "imply", for example. On the other hand in American English "insure" has replaced "ensure", so "insure" in US parlance now has two meanings, and one of them ("to make sure that") may be in the process of being forgotten. I find this hard to take, myself, but a descriptivist has a case here too. It is obvious that most living languages do change over the years by shifts like this one. But the basic structure of the sentence is fairly stable over a long time. I do not think that English could suffer the loss of all its verbs and remain in any reasonable sense the same language. About changes over time...

Really, it's not perplexing. The connection between causation and time is that causation implies time. A cause has to precede its effect. Now why is that? Some philosophers have thought that the proposition 'A cause precedes its effect' is synthetic a priori . Others have thought, more plausibly, that it tells us part of what a cause is , so it's analytic. (A cause might be a certain juxtaposition of conditions, for example. In that case the cause and the effect could be almost simultaneous.) Still others have thought that a cause can occur after its effect. Even then, though, causation has a relationship to time. And there is the so-called "bilking" argument. If a cause can occur after its effect, all we have to do is wait for the effect to occur, and then prevent its cause from occurring. The fact that this is possible shows that there cannot be reverse causation, i.e. causation in which the effect comes before the cause. As to other dimensions - is there an analogue to causation in them? (1) Are...

There are plenty of philosophers who have not agreed with Descartes' line of thought here, though they are not "ancient" philosophers, as Descartes did not propound the "proof", if that is what it is, until 1637, in the Discourse on the Method and, in a slightly different form, in 1641 in the Meditations . You can find some interesting material in the "Objections" to the Meditations , for example the Fifth, by Gassendi, or the Fourth, by Arnauld. Hobbes too, in the Second Objection, makes of Descartes' argument a triviality. How (he asks) can I know that I am thinking? 'It can only be from our ability to conceive an act without its subject. We cannot conceive of jumping without a jumper . . .'. Through the centuries Descartes' dictum has come under even more fire from different directions, for example from A.J. Ayer in Chapter 2 of Language, Truth and Logic . Descartes was only entitled to say that 'There is a thought now,' not 'I think', i.e. 'There is an I and it thinks', because...

There are I think no objections to the way philosophy is taught to undergraduates today in US and UK universities. Courses are on the whole very well taught, there is a an emphasis on clarity and often on originality, and students learn a great deal of respect for decent argument, as well as sound scholarship. Courses on the history of philosophy have never been better, and this is true of courses in other areas as well. I believe you when you say that your school philosophy courses was too broad and "even the professors seemed overwhelmed with the readings." I have noticed this kind of thing before. You are absolutely right that "specialization results in a greater degree of understanding", though there is a place for the well-taught survey course. If I were going to offer a course on three philosophers, I would want the three to have a strong link, so for example a course on "Descartes, Spinoza and Leibniz", "Stewart, Reid and Hamilton", or "Russell, Moore and Wittgenstein".

A lawyer is someone who practises law, or perhaps studies it, an attorney (in the US) or a barrister or solicitor (in the UK), someone who might have little or no interest in the philosophy of law, or in the the concept of law in the abstract. A legal philosopher, on the other hand, is a philosopher, often or typically today an academic person, one who studies and perhaps contributes to the philosophy of law. The philosophy of law is one of the subject areas within philosophy (such as the philosophy of science, the philosophy of religion, ethics, the theory of knowledge, metaphysics, and so on) in which one studies the question 'What is law?' - to be distinguished of course from the question 'What is the law ?' - which is not a philosophical question at all. Or a philosopher of the law might be interested in the question what it is that makes law "valid". There is little doubt what the laws were in say 1935 Germany, e.g. the Nuremberg laws prohibiting the marriage of citizens ("Staatsangehoerigen")...

My answer is a little different from Olilver's. Why do so many scholars and intellectuals think that language is necessary for thought? Answer: Because it really is easier to think about definite rather than indefinite things. But indefinite and formless things also have to be thought about. It takes more of an effort of course to think in a pathfinding sort of a way about something new, and one may or may not be thinking "in" language, whatever that means (muttering to oneself, sub-vocally?) If one is trying to come to an understanding of some hard and new logical or mathematical matter, it may be more like shaping forms in ones mind, and then moving them, and less like chattering in French. If one insists on calling "shaping forms", or whatever the metaphor is "a kind of language", then of course the claim is drained of any content, and with that of any interest. People of say that mathematics is a language, or a "language", something like a language. But it has a function and a status very different...

To me it seems that the use of the word "can't" and its meaning is the same in all three settings (moral, prudential and physical). "Can't" means there's a contradiction in saying that you do the thing you are said not to be able to do. But the contradiction does not appear without the addition of the "laws" or principles of ethics, or the statement of what one wants, or the laws of physics. There is one exception to this principle. "Can't" in logic and logic-derived fields asserts a contradiction without any body of auxiliary propositions. 'I can't lift 1000kg' means that given the facts of my strength and some facts of physics, there is a contradiction in saying that I lift 1000kg.

A helpful answer might be that we see sunsets and mountains and so on as beautiful because they are beautiful. The reason I say that this answer is helpful is twofold. It moves the question away from the bias of a model in which (a) there is no beauty in nature, but (b) we project it onto nature, which together raise the question © 'Why these projections and not others?' That is all built into the question. The second helpful thing, as I see it, about the answer that I have suggested is that it puts the issue squarely on top of the traditional question what beauty is.

You make an important observation for compatibilism. What your analysis does is to show that we can have predictability and law (in a regularity sense) with no implications for individual freedom. My decision to cross the railway track might lead to my death, and it might produce a number that fits the predicted number of deaths on railway lines in a year. Was my decision then not a free one? Hardly, because for that to be the case it has to be coerced or whatever the particular compatibilist line being taken is. The fact that there are h homicides a year in the United States, on average, and that without the homicide I commit the number would be h -1 has no relevance to the freedom or unfreedom of my act. Your point was of central importance to the classical compatibilists, who realized that knowledge and predication of what will happen have no tendency to undermine freedom. I know what I will do, but this could hardly be a reason to say what I will do is not free. It might even be a condition for...

One small point needs attention. If a man is serving a life sentence and is put to death for a different crime, then his life ends and the life sentence has been completed.
