In fact, to avoid long arguments that just go in circles, it would be wise to just forbid using the word "coherent" in discussion at all. Focus on things that you actually agree on the definitions of, or else you'll basically be arguing over whether a taco is a sandwich. | |
| Mar 29, 2020 at 18:18 | comment | added | knzhou | The glib answer is that people use the word "coherence" to mean a hundred different things, usually something like "X is coherent if it makes the equipment I'm currently using work good". So depending on the definition you're using that day, your example could be coherent or not. | |
