Human Nature Presentation

  1. 1. The Human Nature Edmund Navalta Hayk Gevorgyan Michael Fares Seth Ronquillo
  2. 2. Background <ul><li>By definition, the human nature is “the set of logical characteristics, including ways of thinking and behaving, that all human have in common.” </li></ul><ul><li>Many factors contribute to the nature of humans. </li></ul>
  3. 3. Human Nature <ul><li>Philosophies </li></ul><ul><li>Biological Evidence </li></ul><ul><li>Genetics </li></ul><ul><li>Psychology </li></ul><ul><li>Birth Order </li></ul><ul><li>Id </li></ul><ul><li>Human Instinct </li></ul><ul><li>Homosexuality </li></ul>
  4. 4. Philosophies <ul><li>Karl Marx suggested that “humans are capable of making or shaping their own nature to some extent.” </li></ul>
  5. 5. Philosophies <ul><li>Plato suggested that “there was an intellectual soul , resident in the human head, and there was an appetitive beast , resident in the belly and genitals.” </li></ul><ul><ul><li>He said that the soul’s duty is to keep the beast tamed. </li></ul></ul>
  6. 6. Philosophies <ul><li>Edward O. Wilson proposed that the human nature is a collection of genetic patterns of mental development. </li></ul><ul><ul><li>According to him, culture, rituals, art, and such are products, not part, of human nature. </li></ul></ul>
  7. 7. Biological Evidence <ul><li>The e volution of humans as primates from primitive animals gives “the biological basis of [human] social behavior” (sociobiology). </li></ul><ul><ul><li>Humans tend to have primitive behaviors and other social behaviors similar to other animals. </li></ul></ul><ul><li>Human nature contributes to human survival as a part of biological adaptation. </li></ul>
  8. 8. Genetics <ul><li>Genes determine the phenotype (observable quality) of an organism, including humans. </li></ul><ul><ul><li>This includes behavioral qualities. </li></ul></ul><ul><li>The human mind and the human nature are shaped by genes. </li></ul>
  9. 9. Psychology <ul><li>The IQ ‘s of siblings show great variance or similarity depending on genes. </li></ul><ul><li>Even though adoptive siblings have the same nurture during childhood, their IQ diverges during adolescence. </li></ul><ul><li>Identical twins and true siblings have similar IQ’s regardless of the type of nurture. </li></ul>
  10. 10. Psychology
  11. 11. Birth Order <ul><li>Many psychologists speculate that the birth order of siblings affect their individual personalities and intelligences. </li></ul><ul><ul><li>They believe that firstborns are usually smarter so that they will be able to teach their younger siblings ( tutor effect ). </li></ul></ul><ul><ul><li>In a way, it is an adaptation for humans as organisms. </li></ul></ul>
  12. 12. Id <ul><li>Sigmund Freud’s theory describes the id . </li></ul><ul><li>The id reflects the human nature. </li></ul><ul><li>Id is manifestation of instincts. </li></ul>
  13. 13. Human Instinct <ul><li>Humans have both a pleasure-seeking drive and a death drive . </li></ul><ul><ul><li>The pleasure-seeking drive is called Eros or libido and is usually linked to the sexual drive. </li></ul></ul><ul><ul><li>The death drive, or Thanatos , encompasses a person to take risks which could endanger himself and counters the pleasure-seeking drive. </li></ul></ul>
  14. 14. Homosexuality <ul><li>In psychology, the fraternal birth order effect states that the more older brothers a male has, he is more likely to have a homosexual sexual orientation. </li></ul><ul><ul><li>In females, however, there seems to be no effect. </li></ul></ul><ul><li>It is also said that exposure to certain fetal hormones during sex differentiation could influence sexual orientation during adulthood. </li></ul>
  15. 15. Homosexuality
  16. 16. Disproof of Nurture <ul><li>Biological evidence such as evolution and adaptation shows us how human nature is an innate attribute that could determine our mentality and actions. </li></ul><ul><li>The IQ experiment shows how nature dominates nurture. </li></ul><ul><li>The human nature is an inevitable force that can engage one to certain action regardless of his nurture. </li></ul>
  17. 17. Conclusion <ul><li>Human nature is an essential aspect of why humans are the way they are. </li></ul><ul><ul><li>It produces results that can be seen in society today (i.e. homosexuality). </li></ul></ul><ul><li>Both biology and philosophy provide evidence to support this. </li></ul>
