He&#8217;d also been actively interested in logic, botany, astronomy, mineralogy, zoology, law, friendship, and other fields. Including astrology and alchemy. I&#8217;ll get back to that.<\/p>\n<p>A collection of his writings, made in 1899, ran to 38 volumes.<\/p>\n<p>If he&#8217;d lived in my day, I have no idea what he&#8217;d have majored in.<\/p>\n<p>Serious researchers realized that astrology&#8217;s rational predictive usefulness was pretty much nil somewhere around the 1700s.<\/p>\n<p>I&#8217;m a Catholic, so I see it as a form of divination.

These days they&#8217;re known as St. Albertus Magnus and St. Thomas Aquinas in my language.<\/p>\n<p>Stories about Albertus Magnus grew after his death.<\/p>\n<p>One about the philosopher&#8217;s stone is definitely bogus. In &#8220;De Mineral,&#8221; Albertus wrote that turning lead into gold was impossible. As he put it: &#8220;Art alone cannot produce a substantial form.&#8221; That&#8217;s a translation, of course.<\/p>\n<p>Interestingly, it&#8217;s easier to turn gold into lead. In 1901 Frederick Soddy and Ernest Rutherford noticed that radioactive thorium turns into radium.<\/p>\n<p>Rutherford&#8217;s colleagues, John Cockcroft and Ernest Walton, caused the first fully artificial nuclear transmutation in 1932. Since then we&#8217;ve learned how to turn lead into gold. It&#8217;s not practical, though. The process would cost a great deal more than the gold is worth.<sup><a href=\"https:\/\/brendans-island.com\/catholic-citizen\/old-truths-new-aspects\/#1\">1<\/a><\/sup><\/p>\n<h4><a name=\"living\"><\/a>Living in &#8216;The Future&#8217;<\/h4>\n<p><a href=\"http:\/\/davidszondy.com\/futurepast\/future-living.html\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/brendans-island.com\/blogsource\/20170501ff\/20170603-life1911-329.jpg?w=640&#038;ssl=1\" align=\"right\"><\/a>The future isn&#8217;t what it used to be.<\/p>\n<p>On the whole, I think it&#8217;s better than quite a few folks expected in my youth: including the optimistic ones.<\/p>\n<p>Life in &#8216;the future&#8217; isn&#8217;t perfect.
