10236 There is no grounding for mathematics that is more secure than mathematics [Shapiro]
6. Mathematics / B. Foundations for Mathematics / 2. Proof in Mathematics
10256 For intuitionists, proof is inherently informal [Shapiro]

10228 Could infinite structures be apprehended by pattern recognition? [Shapiro]
10230 The 4-pattern is the structure common to all collections of four objects [Shapiro]
10249 The main mathematical structures are algebraic, ordered, and topological [Shapiro]
10273 Some structures are exemplified by both abstract and concrete [Shapiro]

10200 We distinguish realism 'in ontology' (for objects), and 'in truth-value' (for being either true or false) [Shapiro]
10210 If mathematical objects are accepted, then a number of standard principles will follow [Shapiro]
