Title: Greek Science


1
Greek Science
  • Summary and Conclusions

2
Characteristic Features
  • The kosmos perceived to be a natural whole
    gods not denied, but not considered to be active
    in nature. Probably the most important and
    enduring contribution.
  • Nature tends to act the same way, and does
    nothing without a purpose. That is, there are
    laws of nature.
  • Humans can recognize those laws do not need
    divine revelation.

3
Why in Ancient Greece?
  • Prosperity though not necessarily political
    stability
  • Mobility/trade/exploration as venue for
    exchanging ideas
  • commercial prosperity, etc. generated a new class
    of citizens (whose wealth was commercial, not
    landed)
  • allowed for movement of scholars but they were
    not a caste of priests who had a monopoly on
    interpreting the will of the gods.

4
most significantly
  • Scholars and scientists came from all over the
    Greek world that is the interest in the study of
    nature was a common element in Greek urban
    culture (and not just at Athens).
  • A civic tradition of public discussion of issues
    citizens decide, not autocrats and kings.

5
The Decline of Science in the Ancient World
  • The rise of pseudo science
  • Ptolemy on the efficacy of astrology. It would be
    wrong to dismiss this type of astrological
    prediction completely only because it sometimes
    can be wrong. After all we do not discard the art
    of navigation as such simply because it is often
    imperfect...Often there is a problem about the
    foremost and principal fact, the fraction of the
    hour of birth. In general, only observations by a
    "horoscopic" astrolabe at the very moment of
    birth can, for a trained observer, give the exact
    time. Almost all other instruments ... are in
    many ways capable of errors sundials because of
    their incorrect position or the incorrect angle
    of the "gnomon" water clocks because of the
    stoppage and irregular flow of the water.

Materia medica
  • From the Roman scholar, Pliny the Elder
  • But we have shown that the most effective
    protection against snakes is the spittle of a
    feasting person and actual daily experience
    confirms other effective uses of it. We spit
    against illnesses like epilepsy that is we repel
    contagion and the danger of meeting a person lame
    in the right leg. ... for quartan fever the liver
    of a cat killed during the waning moon, preserved
    in salt, to be taken in wine just before attacks.

7
On the decline of ancient science
  • the end of the city-state and of public
    discussion
  • decline in prosperity of commerce and trade of
    stability security
  • alternatively, the formation of barbarian
    kingdoms under an essentially uneducated warrior
    class
  • It is not that science disappears, but what there
    is, is practiced (note the pseudo scientific
    texts) at a very low level.

8
The rise of Christianity
  • the role of the church "(natural) philosophy is
    the handmaiden servant of theology" St.
    Augustine.
  • By default, the Church became the sole source of
    education and literacy.
  • It is not the case that the Church was hostile to
    science, rather it saw the natural order as a
    reflection of God's order.

9
Problems
  • The negative aspect of the church's role in
    "scientific discovery" in this period is the
    formation of a priesthood that controlled
    learning and whose status was closely tied to its
    monopoly of knowledge and education.

10
The monolithic nature of Christian Europe would
prove to be a major cultural constraint only
when cities again became prosperous, commerce
revived and the unitary structure split by the
Reformation could science (in the form we have
seen among the Greeks) emerge with anything like
the vitality we have seen.
