Kind of proves my point LG.Kind of proves my point LG.Exactly, kind of proves my point again LG.
Ah but I did or didn't you notice the very first line of the quote I posted. here it is again, and there I've coloured it for you.Am I. then show me where I err. Sorry,
Modus Ponens Assumes the premise, it has no truth base to start with. In the use of reasoning, how do we know that the premises are true? we can only attempt to classify the reasoning according to the kinds of guarantees that we have about it, how do we know what probabilities to assign to the premises? the answer is that we don’t. This limits the value of those "truths". We don’t know anything for certain; everything is open to doubt.
Also
Modus Ponens are not a foregone conclusion, Vann Mcgee has shown them to be invalid with counterexamples with so called "true" premises and conclusions. So sorry, you fail.So what is certain within a closed system, nothing. From day one on this thread I've been told I can't know for sure that anything is true, which I must add I haven't challenged, The facts we work with are insufficient, observations we make through our physical senses which are themselves unreliable. Thus we do not have by any means sufficient data to use a method of raw logic. The way we assemble ideas is suspect, If our data is neither qualitatively nor quantitatively complete and accurate we are not able to put together absolutely reliable ideas to work with. The data we are using is not able to be elevated to a level of facts. only at most a close approximation Our method of drawing inferences is not reliable. which brings us to two methods of logic: deductive and inductive. As I have stated before, philosophic arguments are not deductive as they are not rigorous and as such cant prove anything. But they can be very powerful.
Deductive logic produces no new information. It is just a set of rules that allow us to cautiously handle information and definitions so that we only introduce conclusions that are directly derivable from the data we begin with.
Inductive logic makes generalisations from accepted data. Since there may be data or situations not included, considered or known, and since there is no way to rule out other possible generalisations not anticipated, induction only produces a degree of certainty. It does not produce absolute truth and is always subject to error. either way it can only be opinion.Then show me where I err, show where the concept of proof applies in regard to philosophy.Oh yes. very familiar.

Oop's I did it again.Then I suggest you take that up with LG he started the thread, and I haven't seen too much rationality, on this thread either, most certainly from(sorry cant say that nothing is certain) LG, Have you read some of his posts, in the religious section. You all appear to know how to word your posts, and appear intelligent by I fear that this is not proof, (oh wow there's that concept of proof again). This here is a reply that a another member made to LG, it kind of says it all in his regard, however hopefully not in anyone else regard here.
Oh yes I agree, a person is always unwelcome when they have an opposing viewpoint, especially when the person has a firm basis for their argument. Being unwelcome happens an awful lot when debating the religious. They too don't like their opinions stepped on, even when they are bullying, inculcating a person to get they opinion across.
I really don't need to be here, (but I will be back if someone replies to my post, as is my prerogative.
You lot just need to accept your wrong once in while.
