“Pressure, no doubt, has always been a most important factor in the metamorphism of rocks; but there is, I think, at present some danger in over-estimating this, and representing a partial statement of truth as the whole truth. Geology, like many human beings, suffered from convulsions in its infancy; now, in its later years, I apprehend an attack of pressure on the brain.” ThinkingYearsHumansImportantWholeScienceHuman BeingsBrainDoubtRocksDangerPressureStatementsFactorsNo DoubtRepresentingInfancyGeologyWhole TruthEstimating Author:Thomas George Bonney
“[Microscopic] evidence cannot be presented ad populum. What is seen with the microscope depends not only upon the instrument and the rock-section, but also upon the brain behind the eye of the observer. Each of us looks at a section with the accumulated experience of his past study. Hence the veteran cannot make the novice see with his eyes; so that what carries conviction to the one may make no appeal to the other. This fact does not always seem to be sufficiently recognized by geologists at large.” LooksMayDoeFactsSeemsEyePastScienceBehindsBrainStudyRocksDependsEvidenceInstrumentsConvictionAppealsHis EyesCarrieAdsSectionsVeteranObserversMicroscopesNovicesGeologist Author:Thomas George Bonney
