Is there a word for "put something to a lower form/level/grade (than it should be)"?
All I can think of are
- cast something low
But I would like to assert the sense that the object deserves more recognition or value.
For example, to a friend who describes humans as mere animals whose behavior is dictated and predicted by biological and evolutionary principles,
You reduce the human race to a mere conglomerate of biological and evolutionary rules.
in the sense that the statement puts something in a lower position, not giving its full value.
