That we can now think of no mechanism for astrology is relevant but unconvincing. No mechanism was known, for example, for continental drift when it was proposed by Wegener. Nevertheless, we see that Wegener was right, and those who objected on the grounds of unavailable mechanism were wrong.

Interpretation

What this quote means

Skepticism towards new ideas should not dismiss their potential truth.

Carl Sagan emphasizes that the absence of a known mechanism should not invalidate a theory. He illustrates this with the example of continental drift, which faced skepticism until evidence validated Wegener's proposal. This quote reminds us that just because we cannot yet explain something does not mean it is false; we must remain open to new ideas and discoveries.

There is a reward structure in science that is very interesting: Our highest honors go to those who disprove the findings of the most revered among us. So Einstein is revered not just because he made so many fundamental contributions to science, but because he found an imperfection in the fundamental contribution of Isaac Newton.

The growth of our understanding of the world through science weakens some of the motivation which makes people believers. But that's not the same thing as saying they're incompatible. It's just that I think some of the traditional reasons for belief, going back thousands of years, are rather undermined.

[Mathematics] is security. Certainty. Truth. Beauty. Insight. Structure. Architecture. I see mathematics, the part of human knowledge that I call mathematics, as one thing - one great, glorious thing. Whether it is differential topology, or functional analysis, or homological algebra, it is all one thing. ... They are intimately interconnected, they are all facets of the same thing. That interconnection, that architecture, is secure truth and is beauty. That's what mathematics is to me.
