Even though I’m a mathematical hobbyist who had four semesters of calculus at a university, I found “An Introduction to Mathematics” to have some tough reading in it – especially, some of the geometric drawings that Whitehead used to illustrate some of his ideas.
According to my understanding, Whitehead wrote this book after the advent of Einstein’s development of Special Relativity, in which the idea of an ether permeating space seemed to have been defeated. Yet, Whitehead says the following (page 158):
“Again, the motion of vibration of a violin string is submitted to a similar harmonic analysis, and so are the vibrations of the ether and the air….”
I wonder what was meant by the use of the term “ether”. Of course, it is possible that Whitehead simply rejected Einstein’s repudiation of a “luminiferous ether”. Einstein’s theory of the relativity of all non-accelerated motion had no use for the theory of an ether as a medium through which light was transmitted.
I like what Whitehead says in the last paragraph of Chap. XVI (page 201):
“(2) Space-perception accompanies our sensations, perhaps all of them, certainly many; but it does not seem to be a necessary quality of things that they should all exist in one space or in any space.”
The idea (very prevalent among materialists) that in order for something to exist, it must exist in a portion of “physical” space, is an idea that is, I am convinced, gravely erroneous, resulting in a most unfortunate devaluing of mind (consciousness), as well as postulating the impossibility of the objective existence of “transcendent spirit”. First of all, if one seeks to sustain such a view as held by many materialists, then what is one to do with mathematical “objects”? If they have any genuine existence, then that existence is OUTSIDE of space-time. If they have no actual existence, then most mathematicians probably operate within the framework of mathematical “superstitions” ��� being deluded into the conviction that the numbers they study and manipulate really exist and are not mere convenient fictions created in their minds (with minds also being convenient fictions). In such an outlook, reality becomes a desert filled with desiccated and inert entities in which hapless humanity finds itself lost in the dilemma of being forced to create innumerable fictions just to cope and thrive in this desert. I believe that this outlook is deserving of ridicule.
Suffice it to say that, given Alfred North Whitehead’s brilliance as a philosopher of the highest rank, his book about mathematics was a somewhat rewarding read for me. Mere mathematical hobbyists, such as myself, might find some portions of “An Introduction to Mathematics” somewhat tough going. It is worth the effort, though.
