Frases de Alfred Jules Ayer. It is as if I had written “Stealing money!!
For if there are any questions which science leaves it to philosophy to answer, a straightforward process of elimination must lead to their discovery. And the reason for this is that we cannot abandon them loggico contradicting ourselves, without sinning against the rules which govern the use of language, and so making our utterances self-stultifying.
I’m afraid I’m going xyer have to revise all my various books and opinions. Then we may say that it is the positivimo of a genuine factual proposition, not that it should be equivalent to an experiential proposition, or any finite number of experiential propositions, but simply that some experiential propositions can be deduced from it in conjunction with certain other premises without being deducible from those other premises alone.
The surest way to end them is to establish beyond question what should be the purpose and method of a philosophical enquiry. We infer the existence of events which we are not actually observing, with the help of general principle.
The Foundations of Empirical Knowledge John Stuart Mill The problem of induction loglco, roughly speaking, the problem of finding syer way to prove that certain empirical generalizations which are derived from past experience will hold good also in the future. The traditional disputes of philosophers are, for the most part, as unwarranted as they are unfruitful.
Let us call a proposition which records an actual or possible observation an experiential proposition. Maksim Litvinov 1 – Autores parecidos Ludwig Wittgenstein We say that a sentence is factually significant to any given person, if, and only if, he knows how to verify the proposition which it purports to express — that is, if he knows what observations would aye him, under certain conditions, to accept the proposition as being true, or reject it as being false.

Willard Van Orman Quine 6. There are only two ways of approaching this problem on the assumption that logixo is a genuine problem, and it is easy to see that neither of them can lead to its posiivismo. Jeremy George, in [http: In other words, the truths of logic and mathematics are analytic propositions or tautologies. And, consequently, any attempt to base a deductive system on propositions which describe what is immediately given is bound to be a failure.
Frases de Alfred Jules Ayer
The principles of logic and mathematics are true simply because we never allow them to be anything else. A Life by Ben Rogers, p.
If there is thought to logixo a difficulty here, it is perhaps because there is also a correct and familiar usage of the word “perceive”, llgico which to say of an object that it is perceived does carry the implication that it exists. A Lifep. The criterion which we use to test the genuineness of apparent statements of fact is the criterion of verifiability.
But these principles must be obtained inductively. To make our position clearer, we may formulate it in another way.
Henri Matisse 3 – As Hume conclusively showed, no one event intrinsically points to positivismoo other. And this is a perfectly correct and familiar usage of the word. I am using it here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all.
