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.
The art of living lies less in eliminating our troubles than in growing with them.
Death and resurrection are what the story is about and had we but eyes to see it, this has been hinted on every page, met us, in some disguise, at every turn, and even been muttered in conversations between such minor characters (if they are minor characters) as the vegetables.
Poverty does not make people terrorists, but terrorists can exploit the frustration it creates and use it as a breeding-ground for violent ideas.
What does God do all day long? He gives birth. From the beginning of eternity, God lies on a maternity bed giving birth to all. God is creating this whole universe full and entire in this present moment.
One must find the source within one's own Self, one must possess it. Everything else was seeking -- a detour, an error.
Most men ebb and flow in wretchedness between the fear of death and the hardship of life; they are unwilling to live, and yet they do not know how to die.
