“Geology, perhaps more than any other department of natural philosophy, is a science of contemplation. It requires no experience or complicated apparatus, no minute processes upon the unknown processes of matter. It demands only an enquiring mind and senses alive to the facts almost everywhere presented in nature. And as it may be acquired without much difficulty, so it may be improved without much painful exertion.”

![“[The] subjective [historical] element in geologic studies accounts for two characteristic types that can be distinguished among geologists: one considering geology as a creative art, the other regarding geology as an exact science.” quote by Reinout Willem van Bemmelen](https://sms4smile.com/quotes/img-quotes/f59/reinout-willem-van-bemmelen-44_accounts_the-subjective-historical-element-in-geo_534299.jpg)
