Ty detta är det herrliga hos menskan att hon kan fatta tingens inre väsen, ej hvad de synas, men hvad de betyda; och verkligheten, hvart vårt öga ser, den är symbolen endast af ett högre.

Esaias Tegnér,Magisterpromotionen i Lund1820

This is Man’s wonderful ability:to be able to grasp the inner essence of phenomena,not what they appear to be, but what they mean,and the reality we see with our eyesis a symbol only of something higher.
