As you say, replied ,Polemarchus: besides, there will be a night-festival, which it will be worth while to look at. We will rise after dinner, and go out to see this festival; and there we shall meet with many of our young men, with whom we can converse. Therefore stay, and do not refuse us. - The Republic of Plato
I've never seen a sentence which has no verb after conjunction while. Is it okay grammatically? And what's the meaning?
I presume it means "during looking at"
