HE said "aether differentiates between things that are "perceptible to the senses" and those which are "realities of the intellect" and not perceptible to the senses."
realities of the intellect include - heat, light and electricity and ethereal matter?
No ether separates those things from heat, electricity and light?
Funny how he has to wait until scientists figure it out. Never does he get a revelation that there is no ether but there is spacetime full of fields and virtual particles and light speed is constant in either direction (they measured light speed to test the ether). And light remains constant even when in motion because time slows down...........
You do realize these these papers you are quoting from are apologetics? People who are in the religion are taking things said and attempting to reconcile ways that they can still be correct. Or attempting to make them not wrong.
The passage I was thinking about is this:
The other kind of human knowledge is that of intelligible things; that is, it consists of intelligible realities which have no outward form or place and which are not sensible. For example, the power of the mind is not sensible, nor are any of the human attributes: These are intelligible realities. Love, likewise, is an intelligible and not a sensible reality. For the ear does not hear these realities, the eye does not see them, the smell does not sense them, the taste does not detect them, the touch does not perceive them. Even the ether, the forces of which are said in natural philosophy to be heat, light, electricity, and magnetism, is an intelligible and not a sensible reality. Likewise, nature itself is an intelligible and not a sensible reality; the human spirit is an intelligible and not a sensible reality.

There's more:
If we were to deny all that is not accessible to the senses, then we would be forced to deny realities which undoubtedly exist. For example, the ether is not sensible, although its reality can be proven. The power of gravity is not sensible, although its existence is likewise undeniable. Whence do we affirm their existence? From their signs. For instance, this light consists in the vibrations of the ether, and from these vibrations we infer its existence.

I found this one also just now:
Similarly in the world of being there exist forces unseen of the eye, such as the force of ether previously mentioned, that cannot be sensed, that cannot be seen. However, from the effects it produceth, that is from its waves and vibrations, light, heat, electricity appear and are made evident. In like manner is the power of growth, of feeling, of understanding, of thought, of memory, of imagination and of discernment; all these inner faculties are unseen of the eye and cannot be sensed, yet all are evident by the effects they produce.

Here's one:
With reference to your question about the “ether,” the various definitions of this word as given in the Oxford English Dictionary all refer to a physical reality, for instance, “an element,” “a substance,” “a medium,” all of which imply a physical and objective reality and, as you say, this was the concept posited by nineteenth century scientists to explain the propagation of light waves. It would have been understood in this sense by the audiences whom ‘Abdu’l‑Bahá was addressing. However, in Chapter XVI of Some Answered Questions, ‘Abdu’l‑Bahá devotes a whole chapter to explaining the difference between things which are “perceptible to the senses” which He calls “objective or sensible,” and realities of the “intellect” which have “no outward form and no place,” and are “not perceptible to the senses.” He gives examples of both “kinds” of “human knowledge.” The first kind is obvious and does not need elaboration. To illustrate the second kind the examples He gives are: love, grief, happiness, the power of the intellect, the human spirit and “ethereal matter.” (In the original Persian the word “ethereal” is the same as “etheric.”) He states clearly that “Even ethereal matter, the forces of which are said in physics to be heat, light, electricity and magnetism, is an intellectual reality, and is not sensible.” In other words, the “ether” is a concept arrived at intellectually to explain certain phenomena. In due course, when scientists failed to confirm the physical existence of the “ether” by delicate experiments, they constructed other intellectual concepts to explain the same phenomena.

As to not disclosing the Physics you described, there was no reason for 'Abdu'l-Baha to talk about them, these references to ether were analogies to explain philosophical or spiritual subjects. The Baha'i Faith is not the domain of science. He may even have been using the understanding of the audience to explicate these subjects, whether they were right or wrong. The same is true in general in the Writings.
It may well be that we shall find some statement is couched in terms familiar to the audience to which it was first addressed, but is strange now to us. For example, in answer to a question about Bahá’u’lláh’s reference to the “fourth heaven” in the Kitáb-i-Íqán, the Guardian’s secretary wrote on his behalf:
As to the ascent of Christ to the fourth heaven, as revealed in the glorious “Book of Íqán,” he [the Guardian] stated that the “fourth heaven” is a term used and a belief held by the early astronomers. The followers of the
Shí‘ih sect likewise held this belief. As the Kitáb-i-Íqán was revealed for the guidance of that sect, this term was used in conformity with the concepts of its followers.

This all looks like baseless apologetics to you, but there are many evidences of the Baha'i Faith of which these seeming contradictions are a drop in the bucket. The evidence in favor of the Baha'i Faith, in my opinion, is overwhelming.
