what had commas to do with it

When I first began writing I felt that writing should go on I still do feel that it should go on but when I first began writing I was completely possessed by the necessity that writing should go on and if writing should go on what had commas and semi-colons to do with it what had commas to do with it what had periods to do with it what had small letters and capitals to do with writing going on which was at the time the most profound need I had in connection with writing.
