Pragmatic ethics defines morality as “whatever works,” attempting to apply scientific and utilitarian methods to human behavior while rejecting any higher authority or ultimate truth. It treats morality as flexible and evidence-based, but it struggles because practitioners cannot agree on what truly “works” or for whom. Materialist pragmatism questions reality, experience, and consciousness, reducing thought, feeling, and logic to mere physiological responses, leaving its moral reasoning unstable. Without God, purpose, or the eternal as a guide, pragmatic ethics builds a moral compass on shifting sands. It leaves us vulnerable to collapse when circumstances change. The Bible highlights that truth and moral wisdom are found in God, not human perception, and that humans cannot know right and wrong apart from Him (John 8:32; James 1:5). While pragmatic ethics may mimic careful reasoning, it ultimately ignores the Creator who embodies existence, truth, and justice. The result is a worldview that risks mistaking convenience for meaning, survival for significance, and leaves the deepest question unresolved: can we ever truly know how to live rightly without God?
When a person removes God, the human soul, the afterlife, personal choice, and all other non-material considerations from his worldview, existence becomes bleak. If we are all cosmic accidents with no purpose in life other than the survival of our race and the propagation of our genes, then morality and right and wrong have no real meaning. The love of science becomes a religion. It explains life, it gives meaning to life (to discover), and it provides an excuse to ignore supernatural phenomena. It is reasonable, then, that such a person would use the methodology of science to attempt to derive a standard for human behavior. This is pragmatic ethics.
Although pragmatic relativism, rooted in a scientific and utilitarian framework, may appear simple, it faces deep philosophical challenges because its practitioners cannot even agree on the definitions of its most basic concepts. Its central idea of “what works” denies any higher authority, grounding ethics solely in human benefit, yet it is nearly undefinable: does it serve the acting individual, society, or some select intellectual elite, and who decides if it truly “works” for the majority?
The nature of reality further complicates pragmatism, as illustrated by Descartes’ “Evil Genius,” which raises the possibility that our experiences may be illusions, leaving pragmatists uncertain whether morality should respond to actual reality or merely to perceived cause-and-effect outcomes. Experience itself is also questioned, since materialist pragmatism rejects the soul, consciousness, and first-person perspective, reducing thought and feeling to mere physiological responses, making even logic and mathematics suspect.
Truth is similarly elusive: while morality is pragmatic and flexible, truth is unknowable, leaving ethics grounded on evidence, reality, and reasoning that cannot be fully trusted. In sum, pragmatic relativism struggles to reconcile its practical aims with profound uncertainty about reality, experience, and truth, leaving its foundational principles internally unstable and philosophically contested.
Pragmatic relativism may offer the illusion of control and clarity, but without God, purpose, or ultimate truth, it leaves us building a moral compass on sand—one storm away from collapse. When what “works” is all that matters, we risk mistaking convenience for meaning, and survival for significance. Perhaps the greatest question it raises is not what ethics should be but whether, without the eternal as our guide, we can ever truly know what it means to live rightly at all.
