| 31. | The proofs of his great topological theorems are intuitionism, which at the time made a stand against set theory.
|
| 32. | The fundamental distinguishing characteristic of intuitionism is its interpretation of what it means for a mathematical statement to be true.
|
| 33. | These include the program of intuitionism founded by constructive set theories such as IZF and the study of topos theory.
|
| 34. | In intuitionism, the term " explicit construction " is not cleanly defined, and that has led to criticisms.
|
| 35. | He became relatively isolated; the development of intuitionism at its source was taken up by his student Arend Heyting.
|
| 36. | Intuitionistic logic was developed by Heyting to study Brouwer's program of intuitionism, in which Brouwer himself avoided formalization.
|
| 37. | Formalized intuitionistic logic was originally developed by Arend Heyting to provide a formal basis for Brouwer's programme of intuitionism.
|
| 38. | Moore's ethical intuitionism has been seen as opening the road for noncognitive views of morality, such as emotivism.
|
| 39. | He specialised initially in logic, publishing books on " Intuitionism " and " Intuitionist logic ".
|
| 40. | Griss was a student of L . E . J . Brouwer and formulated an intuitionism based on a hegelian idealism.
