Furthermore, one could also consider that the above definition is not falsifiable until after the time t, and it is clear that it is impossible to obtain any evidence whatsoever either to support or refute the hypothesis that unexamined ‘grue’ things are blue. /Type /Page The question is such that it is clear that there is no comprehensive solution. /Font << << For example, since birth we observe the sun rising every morning and from that knowledge, we infer that it would rise the following morning. 25 0 obj Clearly, using the words ‘green’ and ‘blue’ would include the implicit definitions of blue and green. /Resources << It is impossible to obtain any evidence whatsoever either to support or refute the hypothesis that ‘grue’ things that are not examined before time t are blue, and this renders the definition unacceptable for use as a basis for a scientific inductive hypothesis. >> Clearly, this is circular. /T1_0 32 0 R << >> endobj Inductive inference suggests a belief in instances of which we have no experience, based on instances of which we do. 10 0 obj /Resources << /Font << endobj, How the failure to consider the limitations of language causes logical errors, How an error of intuition has triumphed over rational logic for almost 100 years, How the irrational belief in the actual existence of infinities has resulted in logical errors, How an irrational belief in the existence of supernatural things overrides logical analysis, A logical analysis of some paradoxes, demonstrating that in many cases the paradox is due to ambiguity of language, Previous miscellaneous posts on various issues, Articles on various matters that do not fit into the above categories, A brief summary of the philosophy underpinning this site, What a formal language is and what can be said within in and what can be said about it, How philosophers have managed to become befuddled by natural language, How the philosopher Irad Kimhi conjures up imaginary difficulties regarding statements of non-existence, Despite claims to the contrary, the reality is that much of mathematics has no logical basis, A derogatory term that mathematicians sometimes apply to the work of others while ignoring the logical inconsistencies in their own work. /Type /Page >> Another principle is that there is no difference between a thing of that class that happens to be examined, and one that is not examined. /Count 13 >> /T1_3 58 0 R On the other hand, crystal balls do not come naturally to people, and there is no “crystal ball practice” that is inherent in our nature, as opposed to the inductive practice discussed by Goodman. /Contents 46 0 R Through experience, we learn that similar causes yield similar effects. /T1_1 31 0 R A commonly accepted re-wording of Goodman’s description is that a thing is ‘grue’: “if it is examined before time t and is green or else if it is not examined before time t and is blue.”. /MediaBox [0 0 432 648] When people reason about matters of fact using induction, they do not think about justifications for their reasoning. endobj A seemingly challenging paradox that is easily resolved by logical analysis.

And the condition that all ‘grue’ things that remain unexamined before time t are blue, generates exactly the same problem as in the previous case.
