Protoscience

Wikipedia, the free encyclopedia - Cite This Source

Protoscience refers to historical philosophical disciplines which existed prior to the development of scientific method, which allowed them to develop into science proper (see prescientific). A standard example is that of alchemy which later became chemistry, or that of astrology which later became astronomy.

By extension, "protoscience" may be used in reference to any "set of beliefs or theories that have not yet been tested adequately by the scientific method but which are otherwise consistent with existing science, a new science working to establish itself as legitimate science".

History of the term

The philosopher of science Thomas Kuhn first used the word in an essay, originally published in 1970:

Science and intuition

Scientific intuition is protoscience, being the detection of new patterns — the eureka moment that allows the breakthrough in problem solving — which initiates a new line of fruitful scientific inquiry.

Isaac Newton is said to have conceived of the acceleration of gravity after seeing an apple fall. This moment of insight into acceleration initiated a phase of protoscience until a hypothesis could be formulated with careful measurements and calculations that allowed experimental falsifiability, (repeatability) and verification.
Charles Darwin conceived of his concept of evolution when on his journey in the ship Beagle to the Galápagos Islands he noticed that finches differed from one island to another. He strongly suspected that the different species of finches must have descended from a single species that was their common ancestor. The protoscientific hypothesis continued to prove useful when other forms of animals, including apes and humans, could be explained as sharing common descent. Only recently, with other scientific fields—especially DNA analysis which verified many of his speculations—did the concept move from protoscience to science with the Theory of Evolution accepted by the consensus of the scientific community today.
