It was lovely to pick up this little book of Einstein essays after recently encountering yet another physics student who had no opinion on the philosophy of physics, just believing in “doing the math.”
This would have been a bizarre view at any other time in the history of physics; Einstein is not only motivated by a philosophical interest in the nature of reality (of course), but thinks deeply about the nature of his own motivation, how it leads him through his reasoning, and his belief in a universe of simple, beautiful truths that encourages him to continue his method of pursuit.
Einstein believes that scientific insights and theories depend on giving “free rein to fancy”, “worming” your way through the big complex mess of data until it sparks an idea that you can mess with—inductive reason from the search for truth and beauty, without which you cannot direct the staid, deductive reasoning of careful logic.
As in all things, imagination is vital, and the postwar avulsion of this “fancy”, core to millennia of science, is a terrible thing.
Anyway. Einstein is an articulate writer on his philosophy and physics history, and adorable in his speeches on other scientists, full of love and admiration for both the great predecessors in his field and for his contemporaries. On his own work he is even cuter, being so modest that almost all mentions of it are in the passive voice (“then arose special relativity…”). When asked to speak on general relativity directly he begins by agreeing to not because of an “exaggerated notion of the importance of my own efforts” but because it’s nice and easy to think about his own stuff instead of immersing himself in the mindset of the historical figures he’s also talked about.
So why the 3 stars when I liked it and I’m normally so generous? Because this is an abridged version of The World As I See It, cutting away the essays on “Judaism, Germany, Politics and Pacifism and sundry other topics” according to the preface. Down with taxonomies, those butcher knives that divide reality! I am all for radical rigorous holism.
