“The true and only goal of science is to reveal unity rather than mechanism.”
Poincaré was a philosopher of science, physicist, mathematician, and engineer. I will refrain from diluting the above quotation by presenting others, but Poincaré took science very seriously and very deeply, so he is worthy of further investigation.
But the above quotation stands on its own. Ultimately science points to its own limitations, when it limits itself to the physical world.
