Once upon a time, people believed that there were Martians wanting to contact us. The NYTimes article today about 1924 fervor about that is darling, yet implicitly dramatizes how fast our technological resourcefulness is evolving, given what scientists are doing now.
Below is a comment I posted today at the article.
Around the time of the Opposition fervor, Edwin Hubble opened a “Copernican” revolution by discovering that all the stars we had seen were merely part of one galaxy—or that most of those “stars” were other galaxies.
So, all of that was a background to what became of philosophy in the 20th century—especially "the question of being" (Heidegger, _Being and Time_, 1927)
We are so early in our evolution of intelligent apprehension.
