The term 'free will' postulates an unproven religious belief that human will is God-given, and completely independent of the environment. The belief is inconsistent with overwhelming evidence that all events, conditions and circumstances in the universe, including human activity, are the result of deterministic processes.
Secularization is the trend toward evidence-based truth, away from religious-based power relationships, role expectations, deity worship, and faith-related strife in the world. A secular worldview and philosophy of life is free of supernatural, spiritual, and mystical elements, thus generally rejects the idea of free will.
The ancient concepts of spirit, spirituality, heart, and soul in the nonmaterial sense are useful and entertaining as metaphor in inspirational and romantic music and literature, but misleading. There is no rational basis for belief in a creator, intelligent design, or free will. Nor is there evidence of a theistic god, an afterlife, a cosmic destiny, a supernatural origin of the universe, an immortal soul, or a religious foundation for morality.
Rational thinking accepts the evidence-based truth that all effects have natural causes. The neurochemical structure of brain circuitry, and encoding of environmental influences (sense data), are required for thought. The human brain receives, stores, and organizes sense data. Chemical synapses, not a supernatural entity, initiate feelings, thoughts, decisions, and actions.
It is time for the term ‘free will’ to be replaced with the term ‘conscious choice.’
