Quote context

[...]

- Have your way. Go to Sparta. Go wherever you will, but don't try to drag the destiny of Troy with you.

- What destiny, to live like a crab in a shell?

- We live well. We tax traders at the sea gate. That's our blood.

- Stupidity! We'll choke on our own fat unless we sail our ships of trade. But how can we, when every harbor is an enemy's?

- Oh, I'm sick of your crazy dreams.

- Careful, brother. Paris has always been able to crack your neck.

- And you can thrash us both.

- Tell him he's a fool, Hector!

- My sons, the fool is the man who makes a quarrel of a debate.

- Paris, I bless your plan to sail to Sparta. I know that I can trust you not to beg for peace.
