So isn't adding "do you think" to "is there a rock" redundant? — ZhouBoTong
No, because one can always think a rock without there being a rock. By the same token, it would be redundant to say I think there are rocks after one already has the experience of extant rocks. Knowledge is a stronger judgement of truth than mere thought.

How did that change how we study the stars? — ZhouBoTong
It may not, although the idea has been forwarded after the advent of QM that reason determines the nature of the experiment which in turn manifests in the experiment determining the nature of that which is being experimented on. This is because observation has been supplanted by the expectation given from mathematical prediction. Overall, however, in the macro world of direct experience, idealism in and of itself doesn’t change how we study, but rather how we understand what we study.
those of alive today have made idealism a part of our lives without even knowing it? — ZhouBoTong
They haven’t “made” it a part of their lives; it is an intrinsic part, exactly half, actually, of the system that makes us human. If you’d said without realizing it, I would be more inclined to agree.

How is it such a massive paradigm shift? It seems to me nothing changed. — ZhouBoTong
If one has no experience of what was, he thinks what is now has always been the norm. History books, the written record and imagination all say differently.

concepts like math were a priori in that they already existed and humans discovered them — ZhouBoTong
The thesis:
Those certain natural relations already existed; that which became mathematical conceptions and the principles legislating their truths are determined in the mind a priori, sufficient to explain and necessary to understand those natural relations.
The proof:
In the absence of a priori knowledge, no figure is possible to conceive from the thought of two lines. Given a 6 and a 3, no concept of 9 is possible from them alone. Given a triangle, it is impossible to conceive from it, that perpendicular lines drawn from the midpoints of each line will meet at a point central to all of them.
With respect to th OP, humans will retain knowledge of post-human rocks in general via their extant experience, but that a priori knowledge is not the same as the direct a posteriori knowledge of a particular set of extant rocks required by the OP. The former is given from intuition, the latter is given from sense.
Think of it this way: instead of asking after rocks post-human, ask about the temperature. There were humans, humans look at thermometers, humans henceforth have indication of a natural phenomenon. Vacate all humans, then ask about the thermometer. Just because there’s no reason to think there’s no natural phenomenon to register on the thermometer doesn’t lend itself to any possible knowledge of what the indication is. Hell, I can’t even tell you the temperature in the next town over and I haven’t been deleted from anything.

And here I had to think my way out of the church without even knowing what idealism was :grin: Doesn't this suggest that I didn't NEED idealism to do that — ZhouBoTong
Absolutely not. You had to reason your way out, which makes explicit your formal transcendental idealism. Unless of course, you simply got kicked out for stealing from the collection plate.
