Quick Thought About Thoughts

So I am reading Manfred by Lord Byron for my 18th/19th Century British Literature course. It is a beautiful poem written eloquently in stage format and I enjoy reading it (really, I do), but I read an entire page and I honestly have no idea what it said due to other things taking priority in my mind. I was too tired to read over it again, so I just continued even after this important realization. Then something caught my attention:

"But I have found our thoughts take wildest flight

Even at the moment when they should array

Themselves in pensive order." (Act 3, lines 43-46)

Coincidence? I will leave that up to you to decide for yourself, but I'd certainly say not.
