God created infinity, and man, unable to understand infinity, had to invent finite sets.
Interpretation
The quote reflects on humanity's struggle to comprehend the concept of infinity, leading to the creation of simplified ideas or systems to manage that complexity.
Gian-Carlo Rota's quote highlights the intrinsic limitation of human understanding when faced with the boundless concept of infinity. It implies that, since humans cannot grasp infinity in its entirety, they resort to framing realities in finite terms or sets, creating frameworks and categories that allow for easier understanding and navigation of the complexities of existence. This reflects a fundamental aspect of human cognition: the necessity to simplify and categorize vast ideas to make them manageable.
In practice
In a philosophy class discussing the nature of existence.
The apex of mathematical achievement occurs when two or more fields which were thought to be entirely unrelated turn out to be closely intertwined. Mathematicians have never decided whether they should feel excited or upset by such events.
Every lecture should state one main point and repeat it over and over, like a theme with variations. An audience is like a herd of cows, moving slowly in the direction they are being driven towards. If we make one point, we have a good chance that the audience will take the right direction; if we make several points, then the cows will scatter all over the field. The audience will lose interest and everyone will go back to the thoughts they interrupted in order to come to our lecture.
A mathematician's work is mostly a tangle of guesswork, analogy, wishful thinking and frustration, and proof, far from being the core of discovery, is more often than not a way of making sure that our minds are not playing tricks.
[In mathematics] There are two kinds of mistakes. There are fatal mistakes that destroy a theory, but there are also contingent ones, which are useful in testing the stability of a theory.
Mathematics is the study of analogies between analogies. All science is. Scientists want to show that things that don't look alike are really the same. That is one of their innermost Freudian motivations. In fact, that is what we mean by understanding.
You belong neither to God nor the state nor me. You belong to yourself and no one else.
I guess he'll have to figure out someday that he is supposed to have this dark side, that it is part of what it means to be human, to have the darkness just as much as the light- that in fact the dark parts make the light visible; without them, the light would disappear. But I guess he has to figure other stuff out first, like how to keep his neck from flopping all over the place and how to sit up.
We live in a society of an imposed forgetfulness, a society that depends on public amnesia.
There is nothing more corrupting, nothing more destructive of the noblest and finest feelings of our nature, than the exercise of unlimited power.
You have a right to experiment with your life. You will make mistakes. And they are right too.
Fear drives the wretched to prayer
