The quoted part of the post's title comes from this Pascal-Emmanuel Gobry piece in The Week The guts of the argument:
And at the level of our society, there is a dramatic pragmatic stake in philosophy. We live in enormously complex, technologically advanced societies where we have the power to do a great deal of harm and a great deal of good. Our societies are built on complex institutions (such as "democracy," "the free market," and "science"), which are in turn premised on ways of looking at the world and on ideas about the world and humanity — in other words, on philosophy.
But we have become like people in a Star Trek episode whose planet is ruled by a benevolent artificial intelligence, and who live such charmed lives as a result that, over generations, they have forgotten how the computer works, so that when it breaks down, they are completely powerless to repair it, and have to call the Enterprise for help. Our entire civilization is built on technology called "philosophy" that, in many ways, we are losing a basic understanding of. . . .
. . .
Serious philosophy is valuable in itself. It is worth studying for its own sake.
But it is also the case that our society is built on ancient philosophy, and that if we forget how it works, very soon, we will break it — or it will break us.
