In thermodynamics, theistic thermodynamics, aka "theological thermodynamics" or "creationist thermodynamics", as compared to “atheistic thermodynamics”, refers to the view or belief that there is a god and that this god (or creator) is involved, in some way, in the origin and ongoing nature of the laws of thermodynamics, two main laws of the universe.
A tell-tale sign of theistic thermodynamics, is the use of the terms: create, creation, creature, creator, or created, which are code for an attempt to frame the laws of thermodynamics around creation myth, theology, and or theism.
In 1874, the famous Tyndall vs Stewart and Tait BAAS debate erupted between John Tyndall, an atheist and materialist, and semi-closeted scientific theists Balfour Stewart and Peter Tait; one result was the followup book The Unseen Universe: Speculations of a Future State (1875) by Stewart and Tait. In 1878, James Maxwell penned his poem "A Paradoxical Ode: After Shelley", his last work, where he gave an ambiguous fence-sitting take on the debate, seemingly siding more on the Percy Shelley side of the fence. This so-called signing off on the matter by Maxwell, might can say, can be defined as the year that thermodynamics, in the scientific community, tipped to the atheistic side of the fence.
In 2015, Philip Ball, in his Invisible: the Dangerous Allure of the Unseen, building on Stewart and Tait's The Unseen Universe, discussed "theological thermodynamics", in respect to the dangers of thinking about god as an invisible man, unseen force, or "higher power".
The following are example of creationist thermodynamics quotes:
- “Known facts with reference to the mechanics of animal and vegetable bodies, [there is] at present in the material world a universal tendency to the dissipation of mechanical energy [and] any restoration of mechanical energy, without more than an equivalent of dissipation, is impossible in inanimate material processes, and is probably never effected by means of organized matter, either endowed with vegetable life or subject to the will of an animated creature.”
- “The point of all of this is that our creator has fashioned laws that are deep seated and broadly applicable, that science is heavily intertwined in our everyday life, frequently without our realization, that we need to break down the compartmentalization of knowledge, that we need to work for a unification of learning, and that we need to understand better the meaning and purpose of life.”
- “The second law of thermodynamics is man’s description of the prior and continuing work of a creator, who also holds the answer to the future destiny of man and the universe.”

- “Consider that when Clausius created U, he was able to reasonably grasp the physical meaning behind it since he based the creation on two comprising properties that he grasped quite well, the vis viva of the moving atoms and the work needed to separate them. In other words, he first learned the pieces than created the whole.”
