Primitive Laws: Explaining The Past And Present

can primitive laws explain

The concept of primitive laws is a topic of ongoing debate in the field of philosophy, with contributions from notable scholars such as Tyler Hildebrand, John Carroll, Tim Maudlin, Eddy Keming Chen, and Sheldon Goldstein. Primitive laws refer to the fundamental rules that govern the behaviour of the natural world. These laws are invoked by scientists to explain the uniformity and regularity observed in nature. However, the question arises as to whether these primitive laws can provide a satisfactory explanation for the complex nature of our world. This topic has led to the emergence of various schools of thought, including primitivism, Humeanism, and non-Humeanism, each offering unique perspectives on the role and limitations of primitive laws in understanding the universe.

The uniformity of nature

The concept of uniformity in nature is integral to the idea of natural law, which holds that there are inherent laws derived from nature and universal moral principles that can be discovered through reason. These laws are thought to be independent of enacted laws or societal norms. In the Western tradition, the concept of natural law was explored by pre-Socratic philosophers, ancient Greek philosophers like Aristotle, and in ancient Roman philosophy by Cicero. It was later expounded upon by Christian philosophers during the Middle Ages and the Renaissance, such as Albert the Great and Thomas Aquinas, who synthesised the ideas into a consistent system.

The idea of natural law has evolved over time and is closely related to the concept of natural rights in the early 21st century. It has been used by Enlightenment-era thinkers like John Locke to challenge the theory of the divine right of kings and justify social contracts, positive law, and government.

While some advocate for the existence of natural laws, others critique the notion. Tyler Hildebrand, in his work "Can Primitive Laws Explain?", challenges the ability of primitive laws to explain the uniformity of nature. He argues that while a primitive law may make something likely, its primitive status does not provide a reason to think that it must describe or give rise to a natural regularity. This critique extends to all theories of governing laws, including Humean laws.

Primitive laws and natural regularity

The concept of primitive laws and their relation to natural regularity is a complex and multifaceted topic that has been explored by various philosophers and scientists. One of the central questions surrounding this topic is whether primitive laws can adequately explain the uniformity and regularities observed in nature.

Primitive laws, also known as primitivism about laws, refer to the idea that certain fundamental principles or elements govern the behaviour of the natural world. These laws are often invoked by scientists to explain their observations and predictions without necessarily providing a deeper metaphysical explanation. For example, Tim Maudlin's concept of Fundamental Laws of Temporal Evolution (FLOTEs) suggests that primitive elements of the universe produce later states from earlier states, which aligns with traditional Newtonian and non-relativistic quantum mechanical theories.

However, the ability of primitive laws to explain natural regularity has been questioned. Some argue that while a primitive law may make a particular outcome likely, it does not necessarily follow that this law gives rise to a natural regularity. This argument suggests that there is a distinction between a law that increases the likelihood of an event and one that inherently gives rise to a uniform or regular occurrence in nature.

Another perspective is offered by the Regularity Theory, which posits that Laws of Nature are mere descriptions of the uniformities or regularities observed in the world. In contrast, the Necessitarian Theory views Laws of Nature as the governing principles that dictate how the natural world behaves. This disagreement between the Regularity Theory and the Necessitarian Theory highlights a profound gulf within contemporary philosophy, with far-reaching implications.

Furthermore, the concept of primitivism about laws is often associated with Humeanism, which suggests that primitive laws or dispositions unfold over time through a process called 'nomic production'. However, Humeanism faces challenges in maintaining its commitment to the absence of necessary connections among distinct entities. Additionally, non-temporal conceptions of production within Humeanism have made the central concept of 'nomic production' more elusive.

In conclusion, the relationship between primitive laws and natural regularity is a subject of ongoing philosophical and scientific inquiry. While primitive laws may provide explanatory power and increase our understanding of natural phenomena, there are differing viewpoints on whether these laws inherently give rise to the uniformities observed in nature.

Fundamental Law of Temporal Evolution (FLOTEs)

Tim Maudlin's idea of a Fundamental Law of Temporal Evolution (FLOTEs) is one of the most intuitive views about the metaphysics of laws of nature. FLOTEs are primitive elements of the universe that produce later states from earlier states. They are at home in traditional Newtonian and non-relativistic quantum mechanical theories, as well as our pre-theoretic conception of the world.

However, it is unclear how FLOTEs can be made to work with relativity. Shifting to relativistic spacetimes poses two threats to FLOTEs. Firstly, the lack of a privileged spacelike hypersurface in relativistic spacetime makes it unclear how to understand what produces what. A survey of several conceptions of the nomic production relation compatible with relativity reveals all of them to be lacking. Secondly, relativity motivates a four-dimensional block universe conception of time, according to which all events that will ever occur already exist. This poses a problem for the idea of FLOTEs as productive sources of change.

In response to these challenges, it has been suggested that even if spacetime is relativistic, FLOTEs can still be understood as primitive and not subject to analysis. Furthermore, it is possible to avoid a reliance on fundamental spacetime by reconceiving the Humean supervenience basis of non-modal facts and primitivist or dispositionalist accounts of nomic production.

Despite these defences, the question remains: if FLOTEs can change, what more fundamental cosmic features are they changing in response to? This is a challenge that contemporary cosmology may be able to answer.

Primitivism and dispositionalism

The concept of primitivism and dispositionalism is explored in the paper "The Metaphysics of Laws: Dispositionalism vs. Primitivism" by Mauro Dorato and Michael Esfeld. The paper compares dispositionalism, a relatively new idea that has gained popularity among metaphysicians and philosophers of science, with primitivism, a more traditional concept.

Primitivism, as defended by John Carroll and Tim Maudlin, treats laws as wholly unanalyzable primitives, or fundamental elements of the universe that produce later states from earlier states. This idea, known as Fundamental Law of Temporal Evolution (FLOTE), is intuitive and aligns with traditional Newtonian and non-relativistic quantum mechanical theories. However, one of the main arguments against primitivism is that it cannot explain the uniformity of nature. While a primitive law may make a certain outcome likely, it does not provide a reason for that outcome to be a natural regularity.

Dispositionalism, on the other hand, is a metaphysics of science that aims to elucidate the foundations of science. According to dispositional realism, or dispositionalism, entities in our world possess irreducibly dispositional properties, often called 'powers', which are the sources of change. Dispositionalism offers a realist account of causation and provides new ways to understand modality, laws of nature, agency, free will, and other key concepts in metaphysics. It is particularly relevant in the context of scientific findings and contemporary physics.

While the distinction between primitivism and dispositionalism is clear in classical mechanics, it becomes less distinct in quantum mechanics due to quantum non-locality. However, dispositionalism still offers advantages over primitivism in the realm of quantum mechanics and contemporary physics. Dispositionalism also provides a novel perspective on the interpretation of quantum theory, suggesting that it offers authoritative and objectively correct prescriptions for how agents should act, rather than a description of the physical world.

Laws of nature and explanatory circularity

The concept of "laws of nature" is a topic that has been extensively discussed in the philosophy of science, with various theories and perspectives emerging over time. One such perspective is primitivism, which suggests that laws of nature are primitive elements of the universe that give rise to later states from earlier states. This idea has been explored by philosophers such as John Carroll and Tim Maudlin, who argue that laws can be treated as unanalyzable primitives, providing explanatory power without the need for supporting metaphysics.

However, the notion of "explanatory circularity" in the context of laws of nature has been a subject of debate, particularly in relation to Humean laws. Humeanism presupposes a mosaic of particular matters of fact on which laws supervene, but it faces the challenge of explanatory circularity, where the explanans (what is intended to explain) includes the explanandum (what is to be explained). This circularity undermines the role of explanations to provide understanding, as it suggests that the content of the explanans is sufficient for the truth of the explanandum.

To address this issue, some scholars have proposed distinguishing between scientific and metaphysical explanations. Loewer, for example, argues that Humean laws do not metaphysically explain elements of the mosaic but do scientifically explain aspects of it, suggesting that there are two notions of explanation, thus avoiding circularity. This move has sparked further discussions and responses, such as Lange's argument that scientific and metaphysical explanations are linked by a transitivity principle, which re-ignites the circularity concern.

Another approach to resolving the circularity issue is to differentiate between the aims of metaphysics and the aims of science. Bhogal suggests that the Humean should make this distinction, offering a response to the explanatory circularity problem. However, this proposal has yet to be fully explored and evaluated.

Overall, the concept of laws of nature and explanatory circularity remains a complex and actively debated topic in the philosophy of science, with ongoing contributions from various scholars and perspectives.

Frequently asked questions

Primitive laws are fundamental elements of the universe that produce later states from earlier states.

Primitive laws can provide explanatory power, but they cannot explain the uniformity of nature on their own. While they can make certain outcomes likely, there is no inherent reason for these outcomes to become natural regularities.

Tim Maudlin's idea of a Fundamental Law of Temporal Evolution (FLOTE) is a primitive law that describes the evolution of the universe from earlier to later states.

If there are only "laws" in the world, then these laws cannot be considered central, and thus they are not laws at all. Therefore, if there are laws of nature, there must also be accidents.

Primitive laws can be understood as a process of 'nomic production' unfolding over time. However, non-temporal conceptions of production make this concept more elusive.
