"same" is an adjective that modifies a noun. Because it is often used with a "back reference", we've learned to add "the". But, the practice has morphed a bit......often, "the" is a forward reference, as in: "Black and White are not the same thing."----then this evolves into "Black and White are not the same."---now what does "the" refer to?
Compare to the usage of words like similar, different, contrasting, and many more:
"Circles and ellipses are similar, but not the same"
