A Reaction

A simple but rather devastating point. It is the policeman manufacturing a bogus piece of evidence to clinch the conviction, the scientist faking a single observation to fill in the last corner of a promising theory.

The 16 ideas from Pascal Engel

4739 In "if and only if" (iff), "if" expresses the sufficient condition, and "only if" the necessary condition [Engel]
4737 Are truth-bearers propositions, or ideas/beliefs, or sentences/utterances? [Engel]
4738 The coherence theory says truth is an internal relationship between groups of truth-bearers [Engel]
4744 We can't explain the corresponding structure of the world except by referring to our thoughts [Engel]
4745 Any coherent set of beliefs can be made more coherent by adding some false beliefs [Engel]
4746 Pragmatism is better understood as a theory of belief than as a theory of truth [Engel]
4750 The redundancy theory gets rid of facts, for 'it is a fact that p' just means 'p' [Engel]
4751 Maybe there is no more to be said about 'true' than there is about the function of 'and' in logic [Engel]
4752 Deflationism must reduce bivalence ('p is true or false') to excluded middle ('p or not-p') [Engel]
4753 Deflationism seems to block philosophers' main occupation, asking metatheoretical questions [Engel]
4755 Deflationism cannot explain why we hold beliefs for reasons [Engel]
4754 Our beliefs are meant to fit the world (i.e. be true), where we want the world to fit our desires [Engel]
4759 Mental states as functions are second-order properties, realised by first-order physical properties [Engel]
4762 The Humean theory of motivation is that beliefs may be motivators as well as desires [Engel]
4763 'Evidentialists' say, and 'voluntarists' deny, that we only believe on the basis of evidence [Engel]
4764 We cannot directly control our beliefs, but we can control the causes of our involuntary beliefs [Engel]
