Hume: Laws of Nature

Hume was correct in his critique of causation as understood by the New Science, a critique deadly to both causal and scientific realism. Getting beyond Hume's critique of causation requires that we call into question the New Science's understanding of causation and replace it with a Neo-Aristotelian account of causal processes. In this paper, I try to point the way to such an account.

The common view that Hume is a regularity theorist about laws of nature isn’t textually well grounded. The texts show that he thinks of them as objective governing principles that could conceivably be violated while still counting as a law of nature. This is a standard view at the time, and Hume borrows it from others. He implies that the best evidence for rational religion is the exceptionless workings of the laws of nature, he argues that suicide isn’t incompatible with (...) the will of God by identifying his will with the laws of nature, and he has Philo argue for the existence of God from the simplicity of the laws governing the world. He sheds some of the theological baggage that laws of nature carry at the time, but not all of it. (shrink)

Gözlemlenenlerden gözlemlen(e)meyenlere diğer bir deyişle genel yasalara ulaşma imkânı veren çıkarım yöntemi olarak tümevarımsal ya da endüktif akıl yürütmenin rasyonel olarak temellendirilmesinin imkanına yönelik soruşturma tarih içerisinde tümevarım sorunu ya da endüksiyon problemi olarak tezahür etmiştir. Bu sorunun temel argümanı tarihsel okumalara baktığımızda İskoç ampirist filozof David Hume tarafından öne sürülmüştür. Hume, tümevarımsal çıkarımlar temelinde, gözlenmeyen meseleler hakkındaki inançlarımıza hangi gerekçelerle ulaştığımızı soruşturmaktadır. Hume soruşturmasının sonucunda gözlemlenenden gözlemlen(e)meyen durumlara ilişkin yapılan olgu meseleleri ile ilgili bütün tümevarımsal akıl yürütmelerin dolaylı ya (...) da dolaysız olarak nedensellik ilişkisine ve bu ilişkinin temelinde yer alan doğanın düzenliliği ilkesi ya da “gelecek her zaman geçmişe benzer” önermesine dayandığını ifade ederek bütün tümevarımsal akıl yürütmelerde ortak olan geleceğin her zaman geçmişe benzeyeceği ifadesinin rasyonel olarak temellendirilmesinin mümkün olmadığını belirtmektedir. Bu bağlamda, çalışmada tümevarımsal akıl yürütme sonucunda ulaşılan sonuca inanmanın hiçbir rasyonel temelinin olamayacağı yönündeki Hume’un görüşü argüman formunda yeniden yapılandırılarak ortaya konulacaktır.

Many contemporary philosophers endorse the Humean-Lewisian Denial of Absolutely Necessary Connections (‘DANC’). Among those philosophers, many deny all or part of the Humean-Lewisian package of views about causation and laws. I argue that they maintain an inconsistent set of views. DANC entails that (1) causal properties and relations are, with a few possible exceptions, always extrinsic to their bearers, (2) nomic properties and relations are, with a few possible exceptions, always extrinsic to their bearers, and (3) causal and nomic properties (...) and relations globally supervene on non-causal, non-nomic properties and relations. Hence, one can’t be a consistent Half-Hearted Humean. Consistency demands giving up the core Humean thesis or facing up to its consequences. The upshot is that we face a stark choice: either there are absolutely necessary connections between distinct existents or it’s "just one damn thing after another.". (shrink)

Hume glaubte, die Kausalverknüpfung sei eine „secret connection“, also eine Verknüpfung, die mindestens unerkennbar, wenn nicht sogar inexis- tent ist. Einige moderne Gegner Humes halten dem entgegen, dass apos- teriorisch entdeckte, metaphysische Notwendigkeit, wie wir sie bei- spielsweise von Kripke und Putnam kennen, diejenige objektiv-reale Verknüpfung in der Welt ist, die auch die Rolle einer kausalen Verknüp- fung in der Welt spielen kann. Ich hinterfrage diese anti-Hume’sche Identifizierung kausaler mit me- taphysischer Notwendigkeit, zeige aber auch einen anderen Weg auf, kausale (...) Kräfte zu postulieren: Wenn unsere willentlichen Handlungen auf Widerstände in der Welt stoßen, haben wir (direkten) Beobachtungszu- gang zu einer Verknüpfung in der Welt, die mindestens einen essentiellen Teil kausaler Kraft ausmacht.

In this paper I will introduce a problem for at least those Humeans who believe that the future is open. More particularly, I will argue that the following aspect of scientific practice cannot be explained by openfuture- Humeanism: There is a distinction between states that we cannot bring about (which are represented in scientific models as nomologically impossible) and states that we merely happen not to bring about. Open-future-Humeanism has no convincing account of this distinction. Therefore it fails to explain (...) why we cannot bring about certain states of affairs, it cannot explain what I call the “recalcitrance of nature”. (shrink)

Metaphysicians play an important role in our understanding of the universe. In recent years, physicists have focussed on finding accurate mathematical formalisms of the evolution of our physical system - if a metaphysician can uncover the metaphysical underpinnings of these formalisms; that is, why these formalisms seem to consistently map the universe, then our understanding of the world and the things in it is greatly enhanced. Science, then, plays a very important role in our project, as the best scientific formalisms (...) provide us with what we, as metaphysicians, should be trying to interpret. In this thesis I examine existing metaphysical views of what a law is (both from a conceptual and from a metaphysical perspective), to show how closely causation is linked to laws, and to provide a priori arguments for and against each of these positions. Ultimately, I aim to provide an analysis of a number of metaphysics of natural laws and causation, apply these accounts to our best scientific theories, and see how these metaphysics fit in with our concepts of cause and law. Although I do not attempt a definitive metaphysical account myself, I conclude that any successful metaphysic will be a broadly Humean one, and furthermore that given the concepts of cause and law that shall be agreed upon, Humean theories allow for there to be causal sequences and laws (in line with our concepts) in the world.
