I stared at him. He stood before me, motionless, with a mocking smile in his eyes; but for all that, for a moment I had an inkling of a fiery, tortured spirit, aiming at something greater than could be conceived by anything that was bound up with the flesh. I had a fleeting glimpse of a pursuit of the ineffable. I looked at the man before me in his shabby clothes, with his great nose and shining eyes, his red beard and untidy hair; and I had a strange sensation that it was only an envelope, and I was in the presence of a disembodied spirit.

"Let us go and look at your pictures," I said.

请教老师：这一句aiming at something greater than could be conceived by anything that was bound up with the flesh.没看懂，

尤其是than 后的比较分句than could be conceived by anything 不会分析，看不懂结构和含义。

麻烦老师详解一下，谢谢！
