I had just asked a comma-related question and, having received an answer, now realize I was asking the wrong question. So, please review the following sentence, arbitrarily taken from Bachelard's The Poetics of Space:
"Memories of the outside world will never have the same tonality as home and, by recalling these memories, we add to our store of dreams."
The aforementioned sentence consists of two independent clauses. Why, then, is there not a comma before "and"? And could there be?
Now, from something I'd recently penned:
"... , and moving forward, actionable (i.e., interpretable and usable) data sets will prove to be a key element of successful marketing strategies."
In this instance, I'd placed the comma prior to the conjunction and treated the entire phrase, "moving forward," as part of that conjunction.
Are both of these examples correct? Are neither (i.e., should there technically be a comma before Bachelard's "and" and before my "moving forward")?
