an essay on man

[Cooliegirly]

I know this might be too much to ask of anyone who volunteers their time to answer people's questions here, but I would appreciate a line by line translation of the following poem. I can find summaries through google but I really want to be able to understand the poem instead of write my paper by repeating what the summary tells me. Please, can anyone help? Even just one or two line would help me a lot.

"Know then thyself, presume not God to scan
The proper study of Mankind is Man.
Placed on this isthmus of a middle state
A Being darkly wise, and rudely great:

With too much knowledge for the Skeptic side,
With too much weakness for the Stoic's pride,
He hangs between; in doubt to act, or rest;
In doubt to deem himself a God, or Beast;
In doubt his Mind or Body to prefer;
Born but to die, and reasoning but to err;

Alike in ignorance, his reason such,
Whether he thinks too little, or too much:
Chaos of Thought and Passion, all confused
Still by himself abused, or disabused;
Created half to rise, and half to fall;
Great lord of all things, yet a prey to all;
Sole judge of truth, in endless error hurled:
The glory, jest, and riddle of the world! "
