And you thought that postmodernism could not touch the field of mathematics. Well it has! As I discovered in Nancy Pearcey’s Book “Total Truth”:
These days’ philosophers no longer regard mathematics as a body of truths. The dominant philosophy of mathematics treats it as a social construction like a game. There are arbitrary rules, neither are true or false, they are just the way we choose to play the game.
This is being taught to school children. A school curriculum developed at Michigan State University for grades 6-8 called “Connected Mathematical Project” says that students should learn that “mathematics is man-made, that it is arbitrary, and good solutions are arrived at by consensus among those who are considered expert”
In Minnesota, teachers are instructed to be tolerant of “multiple mathematical worldviews” in their Minnesota State Statues Governing the Licensing of Teachers, 106, 111. And in New Mexico a recent graduate of high school tells of how a mathematics teacher labelled him a “bigot” for thinking it was important to get the right answer. As long as students worked together in a group and achieved consensus, the teacher insisted, the outcome was acceptable.
If mathematics is arbitrary, then there are no wrong answers, just different perspectives. The simplest, most universal form of knowledge – mathematics – is subject to some radically different worldview interpretations.
If this is happening with mathematics how much more will postmodernism effect more complex fields, biology, economics, law and ethics.
[Simplified for brevity - not an exact quote]
Surely, only the terms used to token mathematics are arbitrary (numbers will be different as spoken / written in other languages), but the qualities that make one (1) or two (2) appear to be universal.
This is dangerous territory we now walk into if the postmodern philosophy of “There is no truth” is the guiding rule for society. I certainly want truth when it comes to the medicine that my doctor prescribes to me, the truth of traffic light operations and I would hope that my bank manager isn’t taken in by this relativistic approach to mathematics either.
The problem at the heart of this philosophy that “There is no truth”, is that this proposition is indefensible. It is, in and of itself, a truth statement and therefore invalidates itself. In other words, they want the statement “There is no truth” to be accepted as truth. If someone were to try to make that statement, then the response should always be “Really, is that true?”
How can you have a meaningful conversation with anyone who holds this view?
All this reminds me of “Values Clarification” which is also being taught to our school children (more universally than this philosophy of mathematics) where they are told that their values and ethics are to be decided by themselves, individually and as a group, and that it is by this moral code that they are to live their lives. The problem arises when they decide that it is ok to cheat on their school tests or that it is ok to hurt others to get what you want. It’s just not a philosophy that can find any traction in reality because, when they grow older and apply what they have learned, they discover that society can and will punish them via the law (a fine or incarceration), if their “values” don’t match those existing already in society.
