Single Idea 19256

[filed under theme 5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic ]

Full Idea

Every attempt to understand anything at least hopes that the very objects of study themselves are subject to a logic more or less identical with that which we employ.

Gist of Idea

Our research always hopes that reality embodies the logic we are employing

A Reaction

The idea that external objects might be subject to a logic has become very unfashionable since Frege, but I love the idea. I'm inclined to think that we derive our logic from the world, so I'm a bit more confident that Peirce.

The 40 ideas from 'Reasoning and the Logic of Things'

19227 Philosophy is a search for real truth [Peirce]
19218 Metaphysics is pointless without exact modern logic [Peirce]
19229 Metaphysics is the science of both experience, and its general laws and types [Peirce]
19219 Metaphysical reasoning is simple enough, but the concepts are very hard [Peirce]
19231 Metaphysics is turning into logic, and logic is becoming mathematics [Peirce]
19228 Sciences concern existence, but philosophy also concerns potential existence [Peirce]
19226 We now know that mathematics only studies hypotheses, not facts [Peirce]
19223 We act on 'full belief' in a crisis, but 'opinion' only operates for trivial actions [Peirce]
19224 Scientists will give up any conclusion, if experience opposes it [Peirce]
19225 I classify science by level of abstraction; principles derive from above, and data from below [Peirce]
19222 Men often answer inner 'whys' by treating unconscious instincts as if they were reasons [Peirce]
19220 We may think animals reason very little, but they hardly ever make mistakes! [Peirce]
19230 People should follow what lies before them, and is within their power [Peirce]
19221 Everybody overrates their own reasoning, so it is clearly superficial [Peirce]
19233 Indexicals are unusual words, because they stimulate the hearer to look around [Peirce]
19234 'Induction' doesn't capture Greek 'epagoge', which is singulars in a mass producing the general [Peirce]
19236 Induction can never prove that laws have no exceptions [Peirce]
19232 In ordinary language a conditional statement assumes that the antecedent is true [Peirce]
19235 How does induction get started? [Peirce]
19238 The logic of relatives relies on objects built of any relations (rather than on classes) [Peirce]
19240 Realism is the belief that there is something in the being of things corresponding to our reasoning [Peirce]
19239 There may be no reality; it's just our one desperate hope of knowing anything [Peirce]
19241 An idea on its own isn't an idea, because they are continuous systems [Peirce]
19237 Deduction is true when the premises facts necessarily make the conclusion fact true [Peirce]
19242 Generalization is the true end of life [Peirce]
19245 We are not inspired by other people's knowledge; a sense of our ignorance motivates study [Peirce]
19244 Chemists rely on a single experiment to establish a fact; repetition is pointless [Peirce]
19243 If each inference slightly reduced our certainty, science would soon be in trouble [Peirce]
19247 The one unpardonable offence in reasoning is to block the route to further truth [Peirce]
19246 'Holding for true' is either practical commitment, or provisional theory [Peirce]
19250 Everything interesting should be recorded, with records that can be rearranged [Peirce]
19251 The worst fallacy in induction is generalising one recondite property from a sample [Peirce]
19249 'Know yourself' is not introspection; it is grasping how others see you [Peirce]
19248 Reasoning involves observation, experiment, and habituation [Peirce]
19252 Objective chance is the property of a distribution [Peirce]
19255 Generalisation is the great law of mind [Peirce]
19254 Our laws of nature may be the result of evolution [Peirce]
19253 We talk of 'association by resemblance' but that is wrong: the association constitutes the resemblance [Peirce]
19257 Whatever is First must be sentient [Peirce]
19256 Our research always hopes that reality embodies the logic we are employing [Peirce]
