Tall D. Advanced Mathematical Thinking

Springer, 1994. — 312 p. — (Mathematics Education Library).This book can help mathematics educators place their research within a broader perspective of the development of mathematical reasoning, and it can help mathematicians see the deep connections between mathematics education research and their own teaching.
It promises to be the standard reference work for many years to come, and a source of both information and inspiration. The book is a most welcome distillation and resource for further development in our collective sense of what constitutes advanced mathematical thinking, and how we can make it accessible to more people.
