The Philosophy Writing Management Triangle Why write books like this to begin with? If your goal is to formulate and express your ideas about philosophy for your own sake then don't worry about an external audience. But, if you anticipate a readership that embraces and appreciates your efforts, what sort of validation of this expectation do you have?
I created a website some years ago that contained original, albeit amateur, historical research on topics that had not been subject to investigations. Then, some time later, I wrote several print-on-demand books based on my site. I did this primarily to insure some records of my efforts survive after I pass away and the site vanishes. I check periodically and find that several of these books are bought each year, but, more importantly, copies reside in a library devoted to these pursuits. I make no money, and consider these books my contributions to these specific areas of activity. I suspect they are rarely checked out and read, but that's OK. The mere fact they exist provides satisfaction.
I have several old friends who are writing what I consider end-of-life projects. I doubt their books will be finished and published, but it gives them a purpose, a reason to persist and grow, even in old age. I suggest to them they have other projects waiting in the wings should they actually finish these books.
What motivates you to write this book? I'm sure you have explained this primary aspect of your project, but I would like to know.
