Sorrybut I've had to correct parts of the sentence; it was not accurate. I am using the most-up-to-date sources on this subject and have four decades of experience doing research on this subject, so I really do want to make that clear. If I see something that I know from my knowledge of the sources is inaccurate in emphasis, I am correcting it. Pinter does not write plays "to express his political causes and beliefs": that is not an accurate statement (according to my research and other published research on the subject in secondary sources as well as primary onesthe works). He explicitly states that that is not how he goes about writing plays or other creative writing. He does that in essays and speeches, but not in his dramatic works per se. Please do not change the emphasis if this is not a field with which you are familiar based on your citation to one page of one secondary source. (I have the source [Grimes]published and in manuscriptand that is not what he states in it.] Thanks.
