high-minded

adj

1. Given to idealism.

   “Walter was the ideal—generous, high-minded, clear in perception; but sensitive, even weak, in action; or, rather, too apt to imagine a world full of lofty aims and noble impulses, and then fancying that was the world in which he had to live.”

2. Refined, cultured, particularly civilized.

   “After the pause for much more self-deprecating laughter and with everyone listening, Salmond rounded off his story on a high-minded note. The hospital near that village is also powered by the same hydro project, he told them.”

3. Proud or arrogant.
4. Magnanimous.
