There are professional philosophers and there are amateur ones. They are, in most cases, very different from one another.
Professional philosophers usually have college degrees in philosophy and, to keep abreast of their profession, they rather faithfully read one or more philosophy journals. Understandably, then, for them, philosophy mostly means what some professional philosopher has written by way of a commentary upon what was lately said by some other professional philosopher in a philosophy journal.
Amateur philosophers, if they have college degrees, have them in some other field. They rarely if ever read philosophy journals. For them, philosophy is a kind of recreational vehicle to which they turn because, being thinking individuals, they delight in reflecting upon several of the highly interesting questions raised in some classical books they have read or provocative conversations they have enjoyed.
Because this book is written by an amateur philosopher, it is not likely professional philosophers will find anything appealing in it. Possibly, it shall appeal to amateur philosophers interested in hearing what a sixty-five year old member of their group has to say on such diverse issues as knowledge, concepts, certitude, "the unknowable," the scientific versus the philosophical method of searching for ultimate realities, relativity, time, space, matter, Zeno of Elea’s bit about Achilles and the tortoise, and paradoxical statements such as: "This statement is not true."
To be sure, because amateurs are self-educated, it is difficult for them to avoid using terminology of their own making, and that necessarily means the amateur is all too often in the awkward position of speaking a tongue known to no one but himself. Curiously, though, those interested in something "off the beaten path" generally find that situation more of an exciting challenge than they do a barrier not worth surmounting. In this, as in every book written by this author, those interested in something off the beaten path will find exactly what they crave.
