Natural theology, once also termed physico-theology,[1] is a type of theology that seeks to provide arguments for theological topics (such as the existence of a deity) based on reason and the discoveries of science, the project of arguing for the existence of God on the basis of observed natural facts, and through natural phenomena viewed as divine, or complexities of nature seen as evidence of a divine plan (see predestination) or Will of God, which includes nature itself.[2]
Besides Hesiod's Works and Days and Zarathushtra's Gathas, Plato gives the earliest surviving account of a natural theology. In the Timaeus, written c. 360 BCE, we read: "We must first investigate concerning [the whole Cosmos] that primary question which has to be investigated at the outset in every case, — namely, whether it has always existed, having no beginning or generation, or whether it has come into existence, having begun from some beginning."[9] In the Laws, in answer to the question as to what arguments justify faith in the gods, Plato affirms: "One is our dogma about the soul...the other is our dogma concerning the ordering of the motion of the stars".[11]
Ancient Rome
Marcus Terentius Varro in his (lost) Antiquitates rerum humanarum et divinarum (Antiquities of Human and Divine Things, 1st century BCE)[12] established a distinction between three kinds of theology: civil (political) (theologia civilis), natural (physical) (theologia naturalis) and mythical (theologia mythica). The theologians of civil theology are "the people", asking how the gods relate to daily life and the state (imperial cult). The theologians of natural theology are the philosophers, asking about the nature of the gods, and the theologians of mythical theology are the poets, crafting mythology.[13]
Raymond of Sabunde's (c. 1385–1436) Theologia Naturalis sive Liber Creaturarum, written 1434–1436, but published posthumously (1484), marks an important stage in the history of natural theology. John Ray (1627–1705) also known as John Wray, was an English naturalist, sometimes referred to as the father of English natural history. He published important works on plants, animals, and natural theology, with the objective "to illustrate the glory of God in the knowledge of the works of nature or creation".[18]Gottfried Wilhelm Leibniz (1646–1716) established another term for natural theology as theodicy, defined exactly as "the justification of God".[19] He viewed the science in a positive light as it supported his personal ethical belief system.[20]
William Derham (1657–1735) continued Ray's tradition of natural theology in two of his own works, Physico-Theology, published during 1713, and Astro-Theology, 1714. These later influenced the work of William Paley.[21]
Nineteenth century
William Paley, author of Natural Theology
In An Essay on the Principle of Population, published during 1798, Thomas Malthus ended with two chapters on natural theology and population. Malthus—a devout Christian—argued that revelation would "damp the soaring wings of intellect", and thus never let "the difficulties and doubts of parts of the scripture" interfere with his work.
William Paley, an important influence on Charles Darwin,[22] gave a well-known rendition of the teleological argument for God. During 1802 he published Natural Theology, or Evidences of the Existence and Attributes of the Deity collected from the Appearances of Nature.[23] In this he described the Watchmaker analogy, for which he is probably best known. His book, which was one of the most-published books of the 19th and 20th centuries, presents a number of teleological and cosmological arguments for the existence of God. The book served as a template for many subsequent natural theologies during the 19th century.[24]
Professor of chemistry and natural history Edward Hitchcock also studied and wrote on natural theology. He attempted to unify and reconcile science and religion, emphasizing geology. His major work of this type was The Religion of Geology and its Connected Sciences (1851).[27]
The Gifford Lectures were established by the will of Adam Lord Gifford to "promote and diffuse the study of Natural Theology in the widest sense of the term—in other words, the knowledge of God." The term "natural theology", as used by Gifford, refers to theology supported by science and not dependent on the miraculous.[28]
David Hume's Dialogues Concerning Natural Religion played a major role in Hume's standpoint on natural theology. Hume's ideas heavily stem from the idea of natural belief.[30] It was stated that, "Hume's doctrine of natural belief allows that certain beliefs are justifiably held by all men without regard to the quality of the evidence which may be produced in their favour".[30] However, Hume's argument also stems from the design argument.[31] The design argument comes from people being labeled as morally good or evil.[31] Hume's argument claims that if we restrict ourselves to the idea of good and evil, that we must also assign this to the designer as well.[31] Hume states, "I will allow that pain or misery in man is compatible with infinite power and goodness in the Deity...A mere possible compatibility is not sufficient. You must prove these pure, unmixt, and uncontrollable attributes...".[31] Hume argues for the idea of a morally perfect deity and requires evidence for anything besides that.[31] Hume's arguments against natural theology had a wide influence on many philosophers.[32]
Charles Darwin's criticism of the theory had a broader impact on scientists and commoners.[32] Darwin's theories showed that humans and animals developed through an evolutionary process. This implied that a chemical reaction was occurring; but it had no influence from the idea of God.[32] However, Darwin's ideas did not erase the question of how the original ideas of matter came to be.[32]
Immanuel Kant and Søren Kierkegaard had similar ideas about natural theology.[33] Kant's ideas focused more on the natural dialect of reason, while Kierkegaard focused more on the dialect of understanding.[33] Both men suggest that "the natural dialect leads to the question of God".[33] Kant argues for the idea that reason leads to the ideas of God as a regulative principle.[33] Kierkegaard argues that the idea of understanding will ultimately lead itself to becoming faith.[clarification needed][34] Both of these men argue that the idea of God cannot be based solely on the idea of reason, that the dialect and ideals will transcend into faith.[clarification needed][33]
Karl Barth opposed the entirety of natural theology. Barth argued that "by starting from such experience, rather that from the gracious revelation through Jesus Christ, we produce a concept of God that is the projection of the highest we know, a construct of human thinking, divorced from salvation history".[29] Barth argues that God is restricted by the construct of human thinking if he is divorced from salvation.[35] Barth also acknowledges that God is knowable because of his grace. Barth's argument stems from the idea of faith rather than reason. Barth held that God can be known only through Jesus Christ, as revealed in scripture, and that any such attempts should be considered idolatry.
Søren Kierkegaard questioned the existence of God, rejecting all rational arguments for God's existence (including the teleological argument) on the grounds that reason is inevitably accompanied by doubt.[36] He proposed that the argument from design does not take into consideration future events which may serve to undermine the proof of God's existence: the argument would never finish proving God's existence.[37] In the Philosophical Fragments, Kierkegaard writes:
The works of God are such that only God can perform them. Just so, but where then are the works of the God? The works from which I would deduce his existence are not directly and immediately given. The wisdom in nature, the goodness, the wisdom in the governance of the world – are all these manifest, perhaps, upon the very face of things? Are we not here confronted with the most terrible temptations to doubt, and is it not impossible finally to dispose of all these doubts? But from such an order of things I will surely not attempt to prove God's existence; and even if I began I would never finish, and would in addition have to live constantly in suspense, lest something so terrible should suddenly happen that my bit of proof would be demolished.
