When sentences commence with more than one introductory adverbial phrase--each of which is independently modifying the finite verb of the main clause--is it acceptable to leave out the conjunction?
Here's an example sentence:
"If you honestly read every page, if you do every exercise, if you follow every principle, you will go through an intellectual experience that will effect a radical change in you." -- from'How to Start Building a Better Vocabulary'
All three introductory adverbials are 'in coordination', in so far as they're all functioning the same way--all modifying 'will go'. But since there are three coordinated 'introductors', shouldn't there be an 'and' injected in between the second and third ones (between 'exercise' and 'if'), indicating that is a standard list? Is the author making an error here?
Thanks in advance for responses.
