Einstein’s work on the importance of the philosophy of physics

“I fully agree with you about the significance and educational value of methodology as well as history and philosophy of science. So many people today—and even professional scientists—seem to me like somebody who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan or specialist and a real seeker after truth.”Einstein. letter to Robert A. Thornton, 7 December 1944. EA 61-574.

“How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. … Concepts that have proven useful in ordering things easily achieve such an authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as ‘necessities of thought,’ ‘a priori givens,’ etc.”

The path of scientific advance is often made impassable for a long time through such errors. For that reason, it is by no means an idle game if we become practiced in analyzing the long-commonplace concepts and exhibiting [revealing, exposing? -Ed.] those circumstances upon which their justification and usefulness depend, how they have grown up, individually, out of the givens of experience. By this means, their all-too-great authority will be broken.” Einstein, 1916, “Memorial notice for Ernst Mach,” Physikalische Zeitschrift 17: 101-02.

為什麼我們需要考慮物理哲學的呢?西方的哲學問題不是爭論數千年沒有結論的嗎?東方古來又真的有科學哲學的嘛!假使從完整的人來看,人真只有理性與感性能夠感覺和經驗,難道除此之外,就不可能有,比方說靈性的嗎?再者講定量的知識,也並非唯一的一種知識,就像物理上多體問題,不是不能形式上用聯立微分方程式來表達,只不過人們還沒有適當的方法直接處理這個數學問題。其次定性描述的學說,舉例說芝諾議論的運動不可能性,引發解決這個悖論之研究,於是自亞里斯多德,經伽利略,… 直到愛因斯坦廣義相對論能用數理描述時空物質運動的關係,不能不說它有極其重要的價值阿!進一步說,如果定量表達所需之數學或許尚不存在,人們細緻的理解也許還沒到位,這又能有甚麼奇怪的呢!!宛如說有些人認為中醫用著陰陽、五行、甲子、經絡等等來描述醫理,就將它歸類為不科學,這真的是有道理的嗎?不要說人們可能不知道那些語詞用於醫理的意義並不同於一般語言的語意想像,這是由於能夠構成一個系統的文字符號,彼此的意指就必須符合思維規律,否則就成了自相矛盾之胡言亂語的了!雖然現今早知道有細菌的存在,也有病理學、解剖學與診斷學等等西醫方法學,然而也有免疫學、老死學和健康醫學種種整體系統的方法論。如此來看中醫事實上是最早試圖將時間、環境、體質、內外原因 … 人身系統的聯繫成一整套學說的了。如果從中國古代名醫所言︰不知易,不足以言醫。或許值得一觀那個淵源流長天地一體之生命哲學的吧!!

愛因斯坦認為物理哲學之所以重要,有著教育上的價值,在於說,物理哲學是關於如何看待,人們所知之大自然的整體科學知識。不僅僅只是物理知識、物理方法以及物理理論與假設之反思的總括。這個哲學嘗試在我們已知的和未知的知識之間建立橋樑,闡述人類思維能力所可能達到的領域極限,並且說明人的這種探索之價值。
