In-Depth Notes on Darwinian Theories of Human Nature

  • Darwinian Theories of Human Nature

  • Arthur Schopenhauer (1788-1860)

    • Characterized as a pessimistic idealist; widely underrated philosopher.

    • Criticized Hegel and sought to revise Kant's philosophy.

    • His ideas influenced Darwin, Nietzsche, Freud; even cited by Hitler.

  • Schopenhauer’s Key Concepts

    • The World as Will and Idea

    • The World as Idea (Vorstellung):

      • All existence is perceived through knowledge, constituted as ideas.

      • "Vorstellung" means representation; we only experience perceptions.

    • The World as Will (Ding an Sich):

      • Each individual experiences their own willing, our bodies are forms of will's manifestation.

      • The essence of existence is Will to Live, described as endless striving.

  • Ground for Pessimism

    • Everything is a manifestation of will; nature operates solely on this impulse.

    • The will to live entails that survival requires the detriment of other life forms (e.g. my survival relies on consuming other beings).

  • Avenues of Escape from Will

    • Ethics:

      • Altruism is the highest ethical pursuit, distinguishing individual from universal respect.

    • Aesthetics:

      • Contemplation through music, art, and drama diverts attention from aggressive impulses.

    • Hinduism: Brahman

    • Buddism: Attachment is the root of suffering

    • Joseph Campbell: The Power of Myth

  • Evolution: General Principles

    • Common Theses:

    • Ancient Earth Thesis: Earth is 4.5 billion years old; universe 12-15 billion.

    • Common Ancestry Thesis: Life originated from non-living matter >3 billion years ago.

    • Progression Thesis: Life evolves from simple unicellular to complex multicellular forms.

    • Natural Selection Thesis: Genetic variations lead to survival adaptations.

  • Natural Selection:

    • Involves:

      • Random variation of traits.

      • Competition and struggle for survival.

      • "Survival of the fittest" principle.

  • Evidence for Evolution:

    • Adaptation of living creatures to their environment.

    • Fossil records showcase gradual species progression.

    • Embryonic replication supports ancestral traits reappearing in embryos.

    • Vestigial organs (e.g., human appendix); rudimentary wings in birds (e.g., penguins).

    • Biochemical similarities and DNA among related species.

  • Timeline of Human Evolution:

    • Begins with pre-human primates, evolving into Australopithecus (e.g., Lucy), and then into Homo species.

    • Key developments include bipedalism, fire use, and stone tools' evolution.

  • Taxonomy of Human Beings:

    • Kingdom: Animal

    • Phylum: Chordata

    • Class: Mammal

    • Order: Primate

    • Family: Hominid

    • Genus: Homo

    • Species: Sapiens (Wise)

  • Influential Figures in Evolutionary Thought:

    • Charles Darwin: Proposed natural selection as the mechanism of evolution.

    • Alfred Russell Wallace: Co-discoverer of natural selection; pushed Darwin to publish.

    • Thomas Huxley: Advocated for ethics counter to 'survival of the fittest'.

    • Social Darwinism (Herbert Spencer): Misappropriated Darwin's ideas in social contexts, promoting harmful ideologies on humanity's worth.

    • Eugenics (Sir Francis Galton): Linked to social policies, promoting selective breeding.

  • Modern Advances and Theory in Evolution:

    • Genetic Basis of Heredity:

    • Gregor Mendel: Established foundational principles of heredity.

    • Richard Dawkins: Advocated for understanding evolution from a genetic perspective in "The Selfish Gene".

  • Reactions Against Behaviorism:

    • Pioneers like Konrad Lorenz and Nikolaas Tinbergen redirected focus from learned behaviors to instinctive and evolutionary behaviors.

    • Evolutionary Psychology: Leda Cosmides and John Tooby explore how evolutionary adaptations shape human psychology and behavior.
