Vernunft vs Gefühl
feeling / sense
'das Gefühl' and 'die Vernunft' often form a contrast. 'das Gefühl' stands for what you feel or intuitively sense. 'die Vernunft' stands for thoughtful, logical, and sensible action. The difference becomes especially clear in decisions: a feeling can be quick and personal, while reason checks whether something is sensible and responsible. People often say that someone is torn between 'Gefühl' and 'Vernunft'.
Vernunft
Im Supermarkt entscheidet meine Mutter aus Vernunft und kauft nicht zu viele Süßigkeiten.
At the supermarket, my mother decides based on reason and does not buy too many sweets.
Gefühl
