uncertainty principle

The principle of causality is one of the most fundamental principles that has been discovered in the history of philosophy and science. Several foundations revolve around this concept. The importance of this principle in classical physics lies in giving physicists the ability to predict phenomena. Furthermore, due to causality is recognized as a fundamental principle in classical physics. With the introduction of the principle of uncertainty, the principle of causality is empirically called into question. Because the claim of the principle of uncertainty in quantum mechanics is that the relationships between fundamental particles are not causally related to each other, and even the behavior of an electron or a subatomic particle is not based on the principle of causality. If we want to identify the speed of particles, we will not be able to identify their state, and if we want to determine their state, we will not be able to identify their speed. The best way to resolve this conflict is to bring the discussion into philosophy, which is exactly what has been done in Islamic philosophy. The concept of causality in Western philosophy seems to be based on Newtonian concepts. But what has been stated in Islamic philosophy is based on metaphysical concepts, and therefore the principle of uncertainty cannot contradict the concept of causality in Islamic philosophy, especially what has been discussed in the philosophy of Avicenna and Allameh Tabataba'i.

This paper revisits the famous 1922 debate between Einstein and Bergson on the nature of time, outlining its central philosophical and scientific points of contention and re-evaluating them in light of developments in quantum physics. Einstein’s conception of time is that of an objective, measurable, and relative dimension within a static four-dimensional “block universe.” In contrast, Bergson conceives of time (durée) as a qualitative, continuous, and creative flow of consciousness that resists reduction to quantitative measurement. The emergence of quantum mechanics, particularly the Heisenberg time–energy uncertainty principle, introduces new complexities that challenge this dichotomy. Quantum features of time, such as intrinsic uncertainty, the indeterminacy of precise moments, and the relational role of the observer, undermine the deterministic framework of classical and relativistic physics and appear, at least superficially, to resonate with Bergson’s critique of spatialized, discrete conceptions of time. However, a closer examination reveals that quantum time remains a quantitative, physical construct distinct from Bergson’s qualitative durée. Drawing upon modern theories such as loop quantum gravity (as articulated by Carlo Rovelli and Lee Smolin) and the insights of contemporary philosophers, this study argues that neither a purely physical nor a purely philosophical approach can, in isolation, account for the multifaceted nature of time. Rather, a comprehensive understanding requires a synthesis of both, recognizing them as complementary perspectives on a single underlying reality.
