pragmatic (adj.)
The opposite of idealistic is pragmatic, a word that describes a philosophy of "doing what works best."
From Greek pragma "deed," the word has historically described philosophers and politicians who were
concerned more with real-world application of ideas than with abstract notions. A pragmatic person
is sensible, grounded, and practical.
