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.

I consider the principle of sufficient reason (henceforth, PSR) as it functions in both Leibniz and Kant. The issue separating these thinkers is a modal status of absolute contingency, which is exempt from PSR insofar as it is neither logically necessary, nor does it necessarily follow from the given causal series. Leibniz’s ambitious metaphysics applies PSR even to God’s choices, which, since they must rest on a reason that makes sense of them, necessarily tend to the creation of the best of all possible worlds. Through PSR, the exercise of human freedom represents the unfolding of a concept God already has chosen, with an eye to the best possible world aligned with the universal intelligibility enjoined by PSR. PSR, in Kant’s critical period, is not a principle of being, but one of mere experience, since any extension of thought beyond possible experience can yield no knowledge. Human agency, for Kant, has an intelligible aspect that is beyond possible experience. Since PSR is only a principle of experience for Kant, the agent in its intelligible aspect is not subject to it. Human free will introduces a special modal category of absolute contingency. Kant provides impetus for a humanism that makes the absolute freedom of the human will a competitor with the sovereignty of God, and also liberates the human will from contemporary ideologies that would subordinate it to natural determinism or group dynamics.
