A poem is that species of composition which opposed to works science by proposing for its immediate object pleasure not truth and from all having this in common with it is?

The question seems to be asking for the completion of a sentence that defines poetry. Let's break down the existing part and build upon it:

The existing sentence: "A poem is that species of composition which opposed to works science by proposing for its immediate object pleasure not truth and from all having this in common with it is?"

Breakdown:

* "A poem is that species of composition..." This sets up a definition of poetry.

* "...which opposed to works science by proposing for its immediate object pleasure not truth..." This contrasts poetry with science, suggesting that science aims for truth while poetry aims for pleasure.

* "...and from all having this in common with it is?" This seems to be an incomplete sentence fragment. It suggests that poetry shares something in common with other things.

Possible completions:

Here are some possible ways to complete the sentence, keeping in mind the focus on pleasure and commonalities:

* "...and from all having this in common with it is the use of language to evoke emotions and experiences.**"

* "...and from all having this in common with it is the power to transcend the mundane and connect us to the sublime.**"

* "...and from all having this in common with it is the ability to create beauty and delight through its arrangement of words.**"

Final thought:

The original sentence is a bit convoluted and grammatically incorrect. But by understanding its intention, we can complete it to create a more concise and meaningful definition of poetry.
