[Meaning] go across, change place.[1]
Aristophanes [writes]:[2] "but swift/swiftly, when you fall into a cul-de-sac, hop/leap/spring to another thought of mind." ['Cul-de-sac' means a situation] where no way forward can be found. He is saying that if the thought-process falls into a cul-de-sac of an enquiry, change to another. Through these [words] he is wishing to poke fun at Sokrates, as someone scorned in his investigations and stuck in a confined space. He is teaching him that if you are at loss [when looking] into anything, quickly hop to another way of thinking. But he who is subordinated to another, obviously being set a test of what is being said, is subordinated.[3]
