Scientific Materialism and Religious Mystery

Scientific materialism and religious mystery form a recurring argument between Godwin Baxter and Archibald McCandless, not a settled contest in which one side simply defeats the other. Baxter rejects the idea that the unknown is inherently sacred and sees nature as an open field of shared gifts; McCandless accepts scientific progress but insists that it repeatedly encounters limits it cannot explain. Their disagreement turns on what should count as mystery—and on whether acknowledging ignorance requires reverence, further investigation, or both.

Medicine, Progress, and Social Conditions

McCandless first presses Baxter to explain the purpose of his research. Baxter says he is refining the techniques of his father, Sir Colin Baxter. McCandless objects that those techniques are outdated: medicine has advanced in the preceding decade through discoveries about microbes and phagocytes, methods for diagnosing and removing brain tumours, and the repair of ulcerous perforation. When Baxter replies that Sir Colin discovered something better, the unanswered challenge makes the disagreement concrete. McCandless measures knowledge by demonstrable medical advances; Baxter claims a discovery beyond the current catalogue but does not, in this exchange, explain it.

The debate then shifts from what surgery can do to what it ought to do. McCandless imagines that Baxter could replace diseased hearts among the rich with healthy hearts from poorer people, and argues that using undamaged organs and limbs from the dead to repair the living could make surgeons saviours. His enthusiasm treats the conversion of anatomical knowledge into intervention as a moral achievement. Baxter, however, describes the heart-transplant proposal as a temptation he declines, and challenges the premise that medicine’s principal purpose is to repair individual bodies. Practitioners, he argues, should unite to prevent illness rather than work separately to profit from cures.

Baxter’s alternative is material and public: sunlight, cleanliness, exercise, fresh air, pure water, a good diet, and roomy, clean houses for everyone. He calls for government to ban work that poisons people or prevents these conditions. The dispute therefore places two uses of scientific knowledge side by side: spectacular technical intervention and preventive reform of the conditions producing disease. McCandless counters that social legislation could damage British industry, allow Germany and the United States to capture its markets, and leave thousands starving; nearly a third of the country’s food, he adds, is imported. His answer invokes economic dependence to make reform seem dangerous, while Baxter makes public health itself a question of collective responsibility.

Creation, Knowledge, and the Sacred

Baxter’s account of creation gives the argument a personal as well as theological dimension. He tells McCandless that watching a creation live, feel, and act independently is a creator’s joy. This feeling reshapes his reading of Genesis: he once could not understand God’s displeasure when Adam and Eve chose to know good and evil, because he regards their choice to become Godlike as something a creator should have been proud to witness. Creation, in this view, reaches its fulfilment not in obedience but in the independence of what has been made.

McCandless answers from the voice of the Shorter Catechism, recalling that Adam and Eve deliberately disobeyed and ate from trees whose fruit was forbidden and harmful. His interpretation makes the boundary between knowledge and transgression morally decisive. Baxter rejects that division: bad religions, like bad governments, depend on mysteries and secrecy. Truth, beauty, and goodness, he argues, are not rare private possessions but ordinary essentials, as available as sunlight, air, and bread. His compact formulation, “God is the universe plus mind,” identifies divinity with the world and the capacity to apprehend it rather than with a hidden realm beyond it.

This is not simply a dispute between faith and scientific facts. Baxter’s claim is that calling the universe mysterious can reveal the limits of the person making the claim: nature withholds nothing essential, and what people do not yet know is not thereby holy. McCandless accepts many of Baxter’s facts while resisting the conclusion drawn from them. His objection is epistemological as well as religious: extending knowledge does not abolish the questions that remain.

The Limits of Scientific Explanation

McCandless develops that objection by moving across different scales of knowledge. The second law of thermodynamics predicts an eventual end in cold porridge, he says, but does not tell anyone how the universe began or whether it began at all. Scientists can describe how galaxies and gases gravitate, yet the nature and operation of gravity remain unexplained. McCandless further argues that modern physicists hide ignorance under formulae, and contrasts knowledge of how species began with the inability to create even the smallest living cell. These examples make scientific knowledge powerful but partial: describing a process is not the same as knowing its ultimate origin or mechanism.

He brings this problem back to Baxter’s own work, referring to the grafting of a baby’s brain into a mother’s skull. The procedure may be clever, McCandless insists, but does not make its practitioner an all-knowing god. Baxter replies that he disputes McCandless’s language, not his facts. That distinction preserves the disagreement rather than resolving it. The two men may share observations about what science can and cannot explain while assigning different meanings to the unexplained: for McCandless, it is evidence of enduring mystery; for Baxter, it is simply ignorance, open to further knowledge and no more sacred than what is already understood.

Baxter’s positive alternative is not omniscience but human interdependence. No single mind, he concedes, can know more than a fraction of past, present, and future existence. Yet he rejects the idea that what remains unknown is more holy or wonderful than what is known. He locates wonder in the things people are and in the loving kindness that creates and supports them, sustains society, and allows people to move freely within it. McCandless immediately adds lust, fear of hunger, and the police to Baxter’s account of what holds society together. His interruption makes the difference in emphasis plain: Baxter stresses generosity and mutual support; McCandless refuses to let that vision conceal coercion and material need.

Rival Explanations and the White Daemon

A later accusation against Baxter recasts scientific materialism in religious and demonic language. A lawyer identifies Bella Baxter with a succession of legendary women and calls her “The White Daemon,” then presents Baxter as a hidden power manipulating her. He describes modern Glasgow as a Babylon of material science and casts Baxter’s medical work, including his presence around morgues and the deathbeds of the poor, as evidence of diabolical influence. The accusation does not establish that Baxter is supernatural; it shows how readily a religious framework can turn scientific practice into an occult threat.

The lawyer claims to present proof coldly and logically, yet the claim follows a denunciation crowded with capital letters and extravagant names for Baxter. That mismatch gives the episode a pointed place in the broader conflict. Baxter objects to mysteries used to protect authority; his accuser answers scientific materialism by supplying a hidden demon behind it. The novel thus makes the struggle over explanation part of its form: assertions about creation, nature, and hidden forces arrive through characters whose confidence and rhetoric are themselves open to scrutiny. Neither scientific achievement nor religious accusation settles every question, but the opposing vocabularies expose what each side fears will remain unknowable.
