The Origin of Life and The Creation of Man: A Philosophical and Theological Overview

Pius XII and Darwin - Grok

Article I.            The Origin of Life

Section 1.01 The Material Origin of Life

(a)    Spontaneous Generation Hypothesis

 This hypothesis holds that life arises through abiogenesis, that is, from the interaction of inorganic materials and forces, gradually diversifying and improving.

A distinction must be made:

From a Philosophical Perspective:

 This hypothesis is untenable, as vital activity surpasses that of inanimate entities and cannot be explained by them. According to the principle of causality, the lesser cannot give rise to the greater.

From a Scientific Perspective:

 It contradicts experimental evidence. The principle omne vivum ex vivo (“all life comes from life”) holds, as demonstrated by Pasteur’s refutation of spontaneous generation.

Aristotle and the Scholastics attributed spontaneous generation to the influence of incorruptible celestial bodies moved by spiritual beings.

(b)   Panspermia Hypothesis

 This hypothesis asserts that the genesis of life may be traced to extraterrestrial origins.

 Main proponents: Richter, Helmholtz, Cohn.

(c)     Eternal Life Hypothesis

 According to this theory, life has always existed on Earth (W. Preyer), even during its incandescent phase (pyrozoans), with inanimate matter regarded as the residue of living beings.

Section 1.02 The Divine Origin of Life

 Life can only be imparted by the One who has power over being, either indirectly, through a seminal force in matter (as in moderate transformism, which holds that God created the world as a seed with certain potentialities that developed over time), or directly, by producing in matter a greater or lesser number of living species.

Article II.          The Evolution of Life

Natural Species: Share a common essence, which suffices to explain their similar real properties.

Systematic Species: Described by naturalists; not all systematic species correspond to true natural species.

Specific Criteria:

Anatomical or physiological characteristics that allow the differentiation of natural species.

Genetic Criterion: Beings that belong to the same species produce fertile offspring.

Qualitative Criterion: Differences between two individuals of the same species are merely quantitative or ornamental.

Human Criterion: Derived from the unity of the human species, as affirmed by philosophy and revelation. Differences perceptible to human reason do not constitute distinct species.

Article III.       The Problem of the Origin of Species (Proposed Solutions)

Section 3.01    Theory of Specific Constancy, or Fixism (Cuvier, Jussieu, Agassiz, Quatrefages):

 God directly created all existing species, which may have undergone accidental variations over the centuries.

Section 3.02 Theory of Intraspecific Transformations (Improper Transformism):

 God created a limited number of natural species. While the specific organisation, determined by the substantial form, remains unchanged, accidental modifications arise from the activity of the vital principle, allowing for the emergence of subspecies.

Section 3.03 Theory of Specific Transformations (Proper Transformism):

 Living species are derived from slow, successive transformations, either from simple organisms (Haeckel’s monera) or from general types that gradually differentiated into classes, orders, genera, and species.

 Among transformists, some acknowledge divine intervention; some extend the theory to the mineral, vegetable, and animal kingdoms, while others restrict it to the vegetable and animal kingdoms.

Section 3.04 Lamarck vs. Darwin

Lamarck

  • Does not extend transformism to humans.
  • Active influence of the environment on variation in forms.
  • Need creates the organ.
  • The environment changes the form (modification occurs in the adult).

Darwin

  • Extends transformism to humans.
  • The environment has no direct influence on form modification; variations arise by chance.
  • The environment acts only as a filter through natural selection.
  • The environment selects the forms (natural selection; germinal modification).

Section 3.05 Critique of Proper Transformism

 If it seeks to explain the origin and perfection of life without God:

  • It contradicts the principle of causality by deriving the more perfect from the less perfect.
  • Even if divine intervention is admitted, it remains unintelligible to derive current individuals and species from primitive types.
  • It is consistently contradicted by experience: specific transformations have never been verified, nor has the inheritance of individual characteristics been demonstrated.
  • Neither necessity nor function can independently create new organs.

Section 3.06 Transformist Arguments

Embryological Argument:

The history of the germ is a summary of the species’ history (Haeckel). Ontogeny (the biological development of an individual from fertilisation to maturity) recapitulates phylogeny (the evolutionary history of a species).

Response: Similar organs are transient and soon develop into specific structures, determined by an internal principle of organisation.

Morphological Argument:

The gradual development of species and the presence of rudimentary organs are evidence of evolution.

Response: Structural similarity does not necessarily imply descent.

Palaeontological Argument:

The history of species can be traced through successive geological layers, which is evidence of descent.

Response: Succession in the fossil record does not necessarily imply descent (post hoc ergo propter hoc). No ancestral form of a class, order, or family has ever been conclusively found.

Article IV.       The Origin of Man

1. The First Man was created by God.

 'Firmly we believe and we confess simply that the true God is… [the] creator of all visible and invisible things, of the spiritual and of the corporal; who by His own omnipotent power at once from the beginning of time created each creature from nothing, spiritual, and corporal, namely, angelic and mundane, and finally the human, constituted as it were, alike of the spirit and the body. '(Fourth Lateran Council, D. 428)

2. Human souls are immediately created by God out of nothing.

'For these reasons the Teaching Authority of the Church does not forbid that, in conformity with the present state of human sciences and sacred theology, research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter - for the Catholic faith obliges us to hold that souls are immediately created by God. However, this must be done in such a way that the reasons for both opinions, that is, those favourable and those unfavourable to evolution, be weighed and judged with the necessary seriousness, moderation and measure, and provided that all are prepared to submit to the judgment of the Church, to whom Christ has given the mission of interpreting authentically the Sacred Scriptures and of defending the dogmas of faith. Some however, rashly transgress this liberty of discussion, when they act as if the origin of the human body from pre-existing and living matter were already completely certain and proved by the facts which have been discovered up to now and by reasoning on those facts, and as if there were nothing in the sources of divine revelation which demands the greatest moderation and caution in this question.' (Pius XII, Humani Generis, n. 36)

3. All humanity descends from Adam and Eve.

'When, however, there is question of another conjectural opinion, namely polygenism, the children of the Church by no means enjoy such liberty. For the faithful cannot embrace that opinion which maintains that either after Adam there existed on this earth true men who did not take their origin through natural generation from him as from the first parent of all, or that Adam represents a certain number of first parents. Now it is in no way apparent how such an opinion can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all and is in everyone as his own.' (Ibid., 37.)
