CHAPTER 2 Flashcards
INTELLECTUAL REVOLUTION
Science is as old as the world
No one can exactly identify when and where science began
From the genesis of time, science has existed
It is always interwoven with the society
Intellectual Revolutions That Defined Society
Greeks speculated about the “nature” in the period before Socrates
600 to 400 BCE
“pre-Socratic”
“non-theological”
“first philosophy”
INTELLECTUAL REVOLUTION
First, the world is a natural whole (supernatural forces do not make things ‘happen’)
Second, there is a natural ‘order’ (there are ‘laws of nature’)
Third, humans can ‘discover’ these laws
3 Characteristics of IR
regularity in the relations or order of phenomena in the world that holds, under a stipulated set of conditions, either universally or in a stated proportion of instances
laws of nature
if it states that some conditions invariably are found together with certain other conditions; and
a law is universal
if it affirms that a stated fraction of cases displaying a given condition will display a certain other condition as well
a law is probabilistic
in either case
a law may be valid even though it obtains only under special circumstances or as a convenient approximation
a law of nature has no logical necessity; rather, it rests directly or indirectly upon the evidence of experience
all pre-Socratic philosophers reached maturity in the colonies, east and west
“colonial” mentality more intellectually adventurous than that found in the mother country
thought in non-theological terms
most were not atheists
viewed the natural order as reflecting some underlying intelligence, the Logos (“the rational principle”)
colonial mentality
of the heavens which described the cosmos as having Earth stationary at the center of the universe
Ptolemaic model
with the Sun at the center of the Solar System
Copernican model
with the Sun at the center of the Solar System
Copernican model
16th century
a watershed in the development of Cosmology
Revolution of Celestial Spheres where a new view of the world is presented: the heliocentric model
copernican revolution
took up an interest in planetary motions
Venus had phases
Jupiter had its own moons in orbit around it, dispelling the idea that everything went around the earth
Neptune
Pope Paul V demanded Galileo to retract his heretical ideas
galileo galilei
phases of venus
thin crescent
full disk
wanes
crescent
Sun, not the Earth, lay at the center of things
a student of the Danish astronomer Tycho Brahe
-accumulated volumes of accurate astronomical observations
-Planetary laws
discovered that the movements of Mars and all the other planets were ellipses rather than circles
johannes kepler
1687
completed the Copernican Revolution and published Philosophiae Naturalis Principia Mathematica
planets are kept in their orbits by the familiar force of gravity
able to derive existing laws to prove the solidity of the heliocentric model
Planetary motions and Universal Law of Gravitation
isaac newton
-People think that AR Wallace was unappreciated and his ideas were stolen by Darwin
-Darwin did not steal from Wallace
-Darwin’s ideas – the Ideas of the Origin–he wrote in 1842
-Early ideas on origin were not towards evolution (Edward Blyth)
1859
-The Origin of Species
-ushered in a new era in the intellectual history of humanity
-credit for the theory of biological evolution
-organisms evolve and discovered the process, natural selection by which they evolve
>completed the Copernican revolution by drawing out for biology the notion of nature as a lawful system of matter in motion
>adaptations and diversity of organisms, the origin of novel and highly organized forms, the origin of humanity itself could now be explained by an orderly process of change governed by natural laws
darwinian revolution
