I hate microsoft. I am getting on quite well with the statement, it seems to be flowing nicely, only one of my sentances is higlighted as a gramatical error thus :
"Working with the hypothetical question of the effects of a hemisphere transplant on Personal Identity as it is currently understood by thinkers such as Parfit and Negel."
Which, I will admit needs work. However, the alternative I was offered reads :
"Thinkers such as Parfit and Negel currently understand working with the hypothetical question of the effects of a hemisphere transplant on Personal Identity as it."

Now really, I ask you.
