Logic is the hygiene the mathematician practices to keep his ideas healthy and strong.
Hermann WeylRead
Without the concepts, methods and results found and developed by previous generations right down to Greek antiquity one cannot understand either the aims or achievements of mathematics in the last 50 years. [Said in 1950]
Interpretation
Understanding mathematics requires knowledge of its historical development and foundational concepts.
Hermann Weyl emphasizes the importance of historical context in understanding contemporary mathematics. He argues that the achievements and aims of modern mathematics are deeply rooted in the concepts and methods established by earlier generations, including those from ancient Greece. Without this understanding, one cannot fully appreciate the significance of mathematical progress made in the past 50 years.
In practice
In a lecture on mathematical philosophy, one might use this quote to emphasize the importance of historical knowledge.
Logic is the hygiene the mathematician practices to keep his ideas healthy and strong.
We are not very pleased when we are forced to accept a mathematical truth by virtue of a complicated chain of formal conclusions and computations, which we traverse blindly, link by link, feeling our way by touch. We want first an overview of the aim and of the road; we want to understand the idea of the proof, the deeper context.
Besides language and music, mathematics is one of the primary manifestations of the free creative power of the human mind.
You can not apply mathematics as long as words still becloud reality.
Besides language and music, it [mathematics] is one of the primary manifestations of the free creative power of the human mind, and it is the universal organ for world understanding through theoretical construction. Mathematics must therefore remain an essential element of the knowledge and abilities which we have to teach, of the culture we have to transmit, to the next generation.
Symmetry, as wide or as narrow as you may define its meaning, is one idea by which man through the ages has tried to comprehend and create order, beauty and perfection.
Let ignorance talk as it will, learning has its value.
While the business of education in Europe consists in lectures upon the ruins of Palmyra and the antiquities of Herculaneum , or in disputes about Hebrew points, Greek particles, or the accent and quantity of the Roman language, the youth of America will be employed in acquiring those branches of knowledge which increase the conveniences of life.
Having enough to eat, being able to educate your children, have reasonably stable employment, and being able to live in a society which isn't collapsing around you-all of these things have been generally eroded.
I remember being in a history lesson and saying to my teacher, 'How come you never talk about black scientists and inventors and pioneers?' And she looked at me and said, 'Because there aren't any.'
Or heritage and ideals, our code and standards - the things we live by and teach our children - are preserved or diminished by how freely we exchange ideas and feelings.
Theory is taught so as to make the student believe that he or she can become a Marxist, a feminist, an Afrocentrist, or a deconstructionist with about the same effort and commitment required in choosing items from a menu.
