Cyclical argument

Anil wonders if the problem is in the ignition switch.

Dipak:I don't think so.

Anil: Then what are you thinking the problem could be?

Dipak: These machines are a problem. We rely on them so much they rule our lives and govern our behavior.

Anil: That's all very well but we must arrive at Chandrapore before dark.

Dipak: You see? If we did not have a machine we would not have set out for Chandrapore.

Anil: I am beginning to see what you are saying. And if we did not have to go to Chandrapore we would not have to rely on the machine.

Dipak: Life was simpler when we walked everywhere.
