He who knows nothing, loves nothing.
He who can do nothing understands nothing.
He who understands nothing is worthless.
But he who understands also loves, notices, sees.
The more knowledge is inherent in a thing,
the greater the love.
Anyone who imagines that all fruits ripen
at the same time as the strawberries
knows nothing about grapes.
