If one were to bring ten of the wisest men in the world together and ask them what was the most stupid thing in existence, they would not be able to discover anything so stupid as astrology.
David HilbertRead
Mathematical science is in my opinion an indivisible whole, an organism whose vitality is conditioned upon the connection of its parts.
Interpretation
Mathematics is an interconnected discipline where all parts rely on each other for vitality.
David Hilbert emphasizes that mathematical science should not be viewed as a mere collection of separate topics, but rather as a cohesive organism. Each part of mathematics is interrelated, and the health of the entire mathematical framework is contingent on the connections and relationships between its various components.
In practice
In a lecture about the importance of mathematical education, you can use this quote to emphasize the cohesiveness of math as a discipline.

The art of doing mathematics consists in finding that special case which contains all the germs of generality.
The further a mathematical theory is developed, the more harmoniously and uniformly does its construction proceed, and unsuspected relations are disclosed between hitherto separated branches of the science.
Wir mussen wissen. Wir werden wissen. We must know. We will know. Inscribed on his tomb in Gilttingen.
Mathematics is a game played according to certain simple rules with meaningless marks on paper.
No one shall expel us from the paradise that Cantor has created for us.
I suppose the one quality in an astronaut more powerful than any other is curiosity. They have to get some place nobody's ever been.
It's hard to imagine anything more interesting than learning how we're woven into the enormous tapestry of existence. Where did our universe come from? How special is our world, and how special are we? We allocate tens of billions of dollars annually to NASA, NSF and academia in search of the answers.
[N]o scientist likes to be criticized. ... But you don't reply to critics: "Wait a minute, wait a minute; this is a really good idea. I'm very fond of it. It's done you no harm. Please don't attack it." That's not the way it goes. The hard but just rule is that if the ideas don't work, you must throw them away. Don't waste any neurons on what doesn't work. Devote those neurons to new ideas that better explain the data. Valid criticism is doing you a favor.
Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.
[About the great synthesis of atomic physics in the 1920s:] It was a heroic time. It was not the doing of any one man; it involved the collaboration of scores of scientists from many different lands. But from the first to last the deeply creative, subtle and critical spirit of Niels Bohr guided, restrained, deepened and finally transmuted the enterprise.
