== Relevance to debates about science and religion ==
Both religious and non-religious scholars have applied the term scientism to individuals associated with New Atheism. Theologian John Haught argued that philosopher Daniel Dennett and other New Atheists subscribe to a belief system of scientific naturalism, which includes the dogma that "only nature, including humans and our creations, is real: that God does not exist; and that science alone can give us complete and reliable knowledge of reality." Haught argued that this belief system is self-refuting since it requires its adherents to assent to beliefs that violate its own stated requirements for knowledge. Christian philosopher Peter Williams argued in 2013 that it is only by conflating science with scientism that New Atheists feel qualified to "pontificate on metaphysical issues". Daniel Dennett responded to religious criticism of his 2006 book Breaking the Spell: Religion as a Natural Phenomenon by saying that accusations of scientism "[are] an all-purpose, wild-card smear ... When someone puts forward a scientific theory that [religious critics] really don't like, they just try to discredit it as 'scientism'. But when it comes to facts, and explanations of facts, science is the only game in town".
Non-religious scholars have also associated New Atheist thought with scientism and/or with positivism. Atheist philosopher Thomas Nagel argued that philosopher Sam Harris conflated all empirical knowledge with scientific knowledge. Marxist literary critic Terry Eagleton argued that Christopher Hitchens possessed an "old-fashioned scientistic notion of what counts as evidence" that reduces knowledge to what can and cannot be proven by scientific procedure. Agnostic philosopher Anthony Kenny has also criticized New Atheist philosopher Alexander Rosenberg's The Atheist's Guide to Reality for resurrecting a self-refuting epistemology of logical positivism and reducing all knowledge of the universe to the discipline of physics.
Michael Shermer, founder of The Skeptics Society, discussed resemblances between scientism and traditional religions, indicating the cult of personality that develops for some scientists.  He defined scientism as a worldview that encompasses natural explanations, eschews supernatural and paranormal speculations, and embraces empiricism and reason.
The Iranian scholar Seyyed Hossein Nasr has stated that in the Western world, many will accept the ideology of modern science, not as "simple ordinary science", but as a replacement for religion.
Gregory R. Peterson wrote that "for many theologians and philosophers, scientism is among the greatest of intellectual sins". Genetic biologist Austin L. Hughes wrote in the conservative journal The New Atlantis that scientism has much in common with superstition: "the stubborn insistence that something ... has powers which no evidence supports."
Repeating common criticisms of logical positivism and verificationism, philosopher of religion Keith Ward has said that scientism is philosophically inconsistent or even self-refuting, as the truth of the two statements "no statements are true unless they can be proven scientifically (or logically)" and "no statements are true unless they can be shown empirically to be true" cannot themselves be proven scientifically, logically, or empirically.

== Philosophy of science ==

=== Anti-scientism ===
Philosopher Paul Feyerabend, who was an enthusiastic proponent of scientism during his youth, later came to characterize science as "an essentially anarchic enterprise" and argued emphatically that science merits no exclusive monopoly of "dealing in knowledge" and that scientists have never operated within a distinct and narrowly self-defined tradition. In his essay Against Method he depicted the process of contemporary scientific education as a mild form of indoctrination, intended for "making the history of science duller, simpler, more uniform, more 'objective' and more easily accessible to treatment by strict and unchanging rules".

[S]cience can stand on its own feet and does not need any help from rationalists, secular humanists, Marxists and similar religious movements; and ... non-scientific cultures, procedures and assumptions can also stand on their own feet and should be allowed to do so ... Science must be protected from ideologies; and societies, especially democratic societies, must be protected from science ... In a democracy scientific institutions, research programmes, and suggestions must therefore be subjected to public control, there must be a separation of state and science just as there is a separation between state and religious institutions, and science should be taught as one view among many and not as the one and only road to truth and reality.

=== Pro-scientism ===
Physicist and philosopher Mario Bunge used the term scientism with a favorable rather than pejorative sense in numerous books published during several decades, and in articles with titles such as "In Defense of Realism and Scientism" and "In Defense of Scientism". Bunge said that scientism should not be equated with inappropriate reductionism, and he dismissed critics of science such as Hayek and Habermas as dogmatists and obscurantists:

To innovate in the young sciences it is necessary to adopt scientism. This is the methodological thesis that the best way of exploring reality is to adopt the scientific method, which may be boiled down to the rule "Check your guesses." Scientism has been explicitly opposed by dogmatists and obscurantists of all stripes, such as the neoliberal ideologist Friedrich von Hayek and the "critical theorist" Jürgen Habermas, a ponderous writer who managed to amalgamate Hegel, Marx, and Freud, and decreed that "science is the ideology of late capitalism."
In 2018, philosophers Maarten Boudry and Massimo Pigliucci co-edited a book titled Science Unlimited? The Challenges of Scientism in which a number of chapters by philosophers and scientists defended scientism. In his chapter "Two Cheers for Scientism", Taner Edis wrote:

It is defensible to claim that scientific, philosophical, and humanistic forms of knowledge are continuous, and that a broadly naturalistic description of our world centered on natural science is correct ... At the very least, such views are legitimate—they may be mistaken, but not because of an elementary error, a confusion of science with ideology, or an offhand dismissal of the humanities. Those of us who argue for such a view are entitled to have two cheers for an ambitious conception of science; and if that is scientism, so be it.
