Whig history
More recently, some scholars have argued that Whig history is essential to the history of science. At one level, "the very term 'the history of science' has itself profoundly Whiggish implications. One may be reasonably clear what 'science' means in the 19th century and most of the 18th century. In the 17th century 'science' has very different meaning. Chemistry, for example, was then inextricably mixed up with alchemy. Before the 17th century dissecting out such a thing as 'science' in anything like the modern sense of the term involves profound distortions". The science historians' rejection of whiggishness has been criticised by some scientists for failing to appreciate "the temporal depth of scientific research".
