In Nyaya-Vaisheshika philosophy, the material cause is considered to be the primary cause of an effect. This means that the material substance from which an effect is produced is its primary cause.

In Samkhya philosophy, there are only three types of causes: the material cause, the efficient cause, and the instrumental cause. The final cause is not included in this system.

Nagarjuna argued that cause and effect are neither real nor unreal. He believed that they are merely conventional distinctions that we make in order to understand the world.

The phenomenological theory is not a theory of consciousness in the same way that the materialist, dualist, and functionalist theories are. It is a method of investigating consciousness that focuses on the subjective experience of consciousness.

The materialist theory of consciousness holds that consciousness is a product of the brain. This means that consciousness is entirely dependent on the brain and cannot exist without it.

The problem of free will is not a problem with the materialist theory of consciousness in the same way that the problem of qualia, the problem of other minds, and the problem of consciousness in non-human animals are. The problem of free will is a philosophical problem that concerns the relationship between consciousness and free will.

The dualist theory of consciousness holds that consciousness is independent of the brain. This means that consciousness can exist without the brain and that the brain is not necessary for consciousness.

The problem of qualia is not a problem with the dualist theory of consciousness in the same way that the problem of interaction, the problem of free will, and the problem of other minds are. The problem of qualia is a philosophical problem that concerns the subjective experience of consciousness.

The functionalist theory of consciousness holds that consciousness is both a product of the brain and independent of the brain. This means that consciousness is dependent on the brain for its existence, but that it is not reducible to the brain.

The problem of free will is not a problem with the functionalist theory of consciousness in the same way that the problem of qualia, the problem of other minds, and the problem of consciousness in non-human animals are. The problem of free will is a philosophical problem that concerns the relationship between consciousness and free will.

Animal consciousness is not a type of consciousness in the same way that phenomenal consciousness, access consciousness, and self-consciousness are. Animal consciousness is the consciousness that is possessed by non-human animals.

The problem of free will is not a problem with the philosophy of consciousness in the same way that the problem of qualia, the problem of other minds, and the problem of consciousness in non-human animals are. The problem of free will is a philosophical problem that concerns the relationship between consciousness and free will.

Formal causation is not a type of causation in the same way that efficient causation, material causation, and final causation are. Formal causation is the type of causation that is responsible for the form or structure of an effect.

Animal consciousness is not a type of consciousness in the same way that phenomenal consciousness, access consciousness, and self-consciousness are. Animal consciousness is the consciousness that is possessed by non-human animals.

The problem of free will is not a problem with the philosophy of consciousness in the same way that the problem of qualia, the problem of other minds, and the problem of consciousness in non-human animals are. The problem of free will is a philosophical problem that concerns the relationship between consciousness and free will.
