For it explains phenomena by something still more unknown than are they, namely by laws of nature resting on forces of nature, one of which is also the vital force. Certainly the whole present condition of all things in the world or in nature must necessarily be capable of explanation from purely physical causes. But such an explanation―supposing one actually succeeded so far as to be able to give it―must always just as necessarily be burdened with two essential imperfections (as it were with two sore points, or like Achilles with the vulnerable heel, or the devil with the cloven foot). On account of these imperfections, everything so explained would still really remain unexplained. The first imperfection is that the \*beginning\* of the chain of causes and effects that explains everything, in other words, of the connected and continuous changes, can positively \*never\* be reached, but, just like the limits of the world in space and time, recedes incessantly and \*in infinitum\*. The second imperfection is that all the efficient causes from which everything is explained always rest on something wholly inexplicable, that is, on the original \*qualities\* of things and the \*natural forces\* that make their appearance in them. By virtue of such forces they produce a definite effect, e.g., weight, hardness, impact, elasticity, heat, electricity, chemical forces, and so on, and such forces remain in every given explanation like an unknown quantity, not to be eliminated at all, in an otherwise perfectly solved algebraical equation. Accordingly there is not a fragment of clay, however little its value, that is not entirely composed of inexplicable qualities. Therefore these two inevitable defects in every purely physical, i.e., causal, explanation indicate that such an explanation can be only \*relatively\* true, and that its whole method and nature cannot be the only, the ultimate and hence sufficient one, in other words, cannot be the method that will ever be able to lead to the satisfactory solution of the difficult riddles of things, and to the true understanding of the world and of existence; but that the \*physical\* explanation, in general and as such, still requires one that is \*metaphysical\*, which would furnish the key to all its assumptions, but for that very reason would have to follow quite a different path. The first step to this is that we should bring to distinct consciousness and firmly retain the distinction between the two, that is, the difference between \*physics\* and \*metaphysics\*. In general this difference rests on the Kantian distinction between \*phenomenon\* and \*thing-in-itself\*. Just because Kant declared the thing-in-itself to be absolutely unknowable, there was, according to him, no \*metaphysics\* at all, but merely immanent knowledge, in other words mere \*physics\*, which can always speak only of phenomena, and together with this a critique of reason which aspires to metaphysics." ―from\_The World as Will and Representation\_. Translated from the German by E. F. J. Payne. In Two Volumes, Volume II, pp. 172-173”” [Arthur Schopenhauer](https://sms4smile.com/quotes/author/arthur-schopenhauer/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Physics alone cannot fully explain reality; it requires metaphysical foundations because explanations always leave unknown causes and an unreachable first cause. **In simple terms:** Physics needs metaphysics to fill gaps in explanations. Key Takeaway Recognize limits of scientific explanations. Themes philosophy science metaphysics epistemology Mood thoughtful inquisitive Type analytical philosophical When to use this quote - academic research - theoretical physics - philosophical debate - education - personal reflection Key Concepts causality first cause unknown forces Questions to Reflect On - What are the limits of scientific explanation? - How do we address the unknown in causality? A Different Perspective Physical explanations always retain hidden assumptions and an infinite regress. ★ ★ ★ ★ ★ No ratings yet [According Metaphysics](https://sms4smile.com/quotes/about/according-metaphysics-1891704/) [Different path](https://sms4smile.com/quotes/about/different-path/) [Existence Physical](https://sms4smile.com/quotes/about/existence-physical-2596797/) [First step](https://sms4smile.com/quotes/about/first-step/) [Fitness](https://sms4smile.com/quotes/about/fitness/) [Metaphysics](https://sms4smile.com/quotes/about/metaphysics/) [Nature](https://sms4smile.com/quotes/about/nature/) [Ontology](https://sms4smile.com/quotes/about/ontology/) [Phenomena Unknown](https://sms4smile.com/quotes/about/phenomena-unknown-5235346/) [Philosophy](https://sms4smile.com/quotes/about/philosophy/) [Physical Explanation](https://sms4smile.com/quotes/about/physical-explanation-5235345/) [Physics](https://sms4smile.com/quotes/about/physics/) [Physics Metaphysics](https://sms4smile.com/quotes/about/physics-metaphysics-390056/) [Schopenhauer](https://sms4smile.com/quotes/about/schopenhauer/) [Science](https://sms4smile.com/quotes/about/science/) [Space and time](https://sms4smile.com/quotes/about/space-and-time/) [True understanding](https://sms4smile.com/quotes/about/true-understanding/) ## Related quotes > [Liberty, according to my metaphysics is a self-determining power in an intellectual agent.
