| Jun 5, 2013 at 3:30 | comment | added | Filippo Alberto Edoardo | @David: Well, the thread is about object that "can't be defined without making choices so far" and before inventing singular homology, it was so for the simplicial one. | |

(I thought about this and other "big" examples but every other time I hesitate and choose discretion). The above "Question" is somewhat fractional, it represents a grand theme at the root of advanced mathematics. | |

| May 21, 2013 at 2:38 | comment | added | David Corwin | Then I don't feel this example fits the thread. This thread is about objects that can't be defined without making choices. The existence of singular cohomology shows that it can be defined without making choices. | |
