Yes to all, except 4, because after looking over the other answers, I'm curious if you actually meant that today's science would become tomorrow's " folly " and that " superstition " may not have been the best word to use ( Unless you actually meant it in the common sense )
Great comment. You actually addressed an issue that I wanted to see if anyone would catch. I.e. what did I even mean by the words that I chose. In terms of superstiation I meant the following definition of the word:
"a widely held but unjustified belief in supernatural causation leading to certain consequences of an action or event, or a practice based on such a belief."
This is of course is one type of definition of the word and not THE definition of it. Further, the word differs from language to language and culture to culture so that some of it may be based on the people of a particular generation and how they view previous generations.
For example, in our generation we may rightly have the ability to look through history and the use of technology not previously developed and come to the conclusion that certain concepts of past generations were
"unjustified belief in supernatural causation." Yet, a previous generation,
"using their own language and idiom" may respond:
"We were not using unjustified belief in supernatural causation - in our day what we were doing is equivalent to what you call in your day science. We had our our scientific method and we did the research and both the method and our research pointed to the conclusions we came to. You guys simply have history, that came after us, and technology that we didn't have available to to come to the conclusions you have arrived at just as the generations before us didn't have we had. If you had lived during our time, you and all of your modern day researchers would have come to the same conclusions we did if you lived under our conditions."
Because we can't dictate how future generations interpret our findings, research, and developments of our generation (possibly because even our languages could be extinct or dead langauges in the future) they may also define our generation as holding by
"unjustified belief in supernatural causation." Just as some elements of Alchemy, Atronomy, Astrology, etc. were once ruled as "superstition" while other parts have passed through the filter of more advanced analysis and found to be reasonable and acceptable. Further to this is that some ancient authors considered the study of the "Source of Creation" as a discipline of science. Rabbi Mosheh ben-Maimon (1135 to 1204) in his day called it (מדע אלהות). Thus, he claimed that the only way to understand this type of "science" was to know various disciplines such as mathematics, physics, chemistry, astronomy, etc. There are some who would argue today against this.
A good example of this could be - 10,000 years in the future a generation may exist that is able to travel through intersteller space. Because our generation and previous generations have never done this, as far as we know, in 10,000 years they may study what they think they understand about the current ideas of how to potentially do intersteller travel and say what is proposed in our generation was
"unjustified belief in supernatural causation." Again, if we could communicate with them we could argue, no it was the science of our day, yet they may interpret it as superstiation - based on our understanding of what we are even saying.
Again, thans for the great comment.
