Quae ignoramus, aspernantur.What we do not know, we reject.
German
Man muß die Suppe erst kosten, ehe man sie lobt.You have to taste the soup before you praise it.
Czech
Kdo co neviděl, neumí to dobře malovati; kdo co nezkusil, neumí o tom povídati.He that hath not seen it cannot paint it well; he that hath not tried it cannot speak of it.
Kdo nic nezkusil, nic neví.Who has not tried anything, knows nothing.
Kdo sám nezkusil, jinému nerozumí.He who has not tried it himself does not understand the other.
