Abstract:People have different confidence in different propositions，On this basis, the concept of bet365 sign up bonus code degree in contemporary epistemology was formed，That is, bet365 sign up bonus code has degrees。The argument for degree of bet365 sign up bonus code is obscure，Both its common sense argument and its linguistic argument confuse bet365 sign up bonus code with confidence。The concept of bet365 sign up bonus code priority believes that bet365 sign up bonus code is a degree of bet365 sign up bonus code above a certain critical value，The lottery paradox and the preface paradox disprove this critical value theory。Based on the distinction between "ontology" and "characteristics"，The ontology of bet365 sign up bonus code has no degree，Confidence as a characteristic of bet365 sign up bonus code has degrees，It represents the firmness of the subject’s bet365 sign up bonus code。The relationship between bet365 sign up bonus code and confidence is that bet365 sign up bonus code takes precedence，Because confidence is a modal propositional bet365 sign up bonus code。
