Vitalism vs. Mechanistic Philosophy of Science
Limitations of Science
• Severely limits the parameters that can be studied • Science is mechanistic
• Parameters MUST be “measurable” • Observations can be statistically tested • Experiments must be repeatable
• Examples of the Limitations of Science
Scientific Method
1. 2. 3. 4. Initial OBSERVATIONS Formulation of QUESTIONS Generation of a testable HYPOTHESIS (= a tentative explanation) and an alternative hypothesis Making of PREDICTIONS using deductive reasoning
States what results are expected if the hypothesis is correct. An “If ______, then _____” process
5.
TESTING through controlled experiments and unbiased observations
Experiments and results must be repeatable and can be validated by other studies Use of statistical tests “Falsify or support hypothesis” REMEMBER THAT SCIENCE CANNOT PROVE HYPOTHESIS WITH ABSOLUTE CERTAINTY
General Properties of Life
1. ORDER
• Arrangement of parts • Chronology of Events (E.g. Stages of Embryonic Development) • Levels of Biological Organization
Subatomic particles → Atom → Organelle → Cell → Tissues → Organs → Organ System → Multicellular Organism → Population → Community → Ecosystem → Biosphere
2. GROWTH AND DEVELOPMENT
• Growth – increase in size
