Only now did I recognize the reciprocal relationship which exits between manufacturing power and the national system of transportation, and that the one can never develop to its fullest without the other.

The relationship I have to my fatherland is like that of mothers with crippled children: they love them all the more, the more crippled they are. Germany is the background of all my plans, the return to Germany.

The concentration and reciprocal effect of industry and agriculture conjoin in a growth of productive powers, which increases more in geometrical than in arithmetical proportion.

Friedrich List Quotes
