Do not try to come up with a thesis before writing. Instead, write first.

Read one page about his life. Then, write one paragraph.
I am pretty sure that you can read a page and then write a paragraph, right? Easy, easy!!

Next, read some article someone wrote about him -- anything that interests you -- and write a paragraph that explains the main idea of that article.

Next, do the same thing for another article.

You will have 3 paragraphs when you do that, and THEN it will be time to look at them and see what theme they all share.

For example, I wrote an essay about Deepak Chopra, and when I had writeen 3 different paragraphs abotu 3 different articles other people had writeen, I looked at them and discovered a theme: Deepak Chopra is better described as a poet than as a scientist.

Many people would disagree with that, and that is what makes it a good thesis statement. But I was only able to think of it AFTER I wrote 3 paragraphs about 3 different articles.

how did Blake biography affects. The way he looked to the world as seem the poem?
How did the way Blake's life story, as told in his biography, affect the way he looked at the world and write about it in his poetry?

Is this what you mean?
Just start writing those paragraphs. You can do it!
