Reddit reviews The Web of Belief

For more on Quine's holism, you could read the standard text although it's rather, dull, compared to word and object. Alternately just try his SEP page: http://plato.stanford.edu/entries/quine/#ObsSen

For the better part of Quine's life, he was an externalist about justification, taking it to be naturalizable, in terms of some sort of account of how certain beliefs prompt certain kinds of behavior. Quine later drops this for a weaker naturalism not mostly due to problems in epistemology, but problems with intension when dealing with belief and mental states in philosophy of mind. Or at least, that was what I think the main motivator was. His own explanation was that he simply couldn't analyze normativity in a naturalistic manner and consented that it had to be preserved anyway if any study of psychology or science was to be sensible. I have doubts that he cared about epistemology this much though. In any case, barring analyses of the term "knowledge" or "justification", Quine's idea of the two was strictly coherentist. He did not think there were basic, foundational theses which could not be doubted rationally by an agent, rather, every belief in an agent's web depended on every other belief, and if one was weakened, the whole was effected. If you asked someone for the reasons they believe something, they will eventually take you around in a circle, rather than getting down to fundamental beliefs which themselves don't require a reason.

Opa, peraí amigo. Assim não né.

Você não pode ter modelos distintos para analizar eventos prévios e posteriores. Se você têm dois modelos, você não têm nenhum.

O que o /u/celtiberian666 explicou é, em termos técnicos, o modelo hipotético-dedutivo, popularmente chamado de "método científico". O método possue características explicativas (focadas em analisar o passado) e características preditivas (focadas no futuro).

Concordo com ele que o problema neste cenário é que o número de agentes e de eventos de entrada com influência no resultado final é grande e matematicamente difícil para se prever. Aliás, se você acha que consegue prever, páre tudo, torne-se um quantitative analyst, programe um punhado de bots e vá curtir a vida enquanto você fica rico.

Se tiver interesse em se aprofundar no assunto sobre o por que não dá faz sentido desvincular em dois modelos, recomendo qualquer livro introdutório à filosofia e/ou à métodos científicos. Um que gosto muito é o The Web of Belief (QUINE).

Unrelated, but did you recently read this, by any chance?

Nevermind.
Willard Van Orman Quine, The Web of Belief.

I like it. Being a physics major with philosophy interest made it a fun read for me, personally. Your images really shine. If I had to criticize, I'd say pay some more attention to the flow and structure in the first couple of paragraphs and the last one. Why is Mr. A important?

On a side note, this reminds me a lot of The web of belief, which was assigned reading for my freshman philosophy course.
