Locke became personal physician to Anthony Ashley Cooper (1621-1683) (Lord Ashley), a leading English political figure during the 1670's and 1680's. [[CiteRef::Dunn (2003)]] He was an early member of the Royal Society and knew most of the major English natural philosophers, including [[Isaac Newton]] (1643-1727) and some continental ones as well. This community was concerned with arguing for the reliability of observation and experiment as a means of acquiring knowledge as opposed to Aristotelian intuition or Cartesian rationalism. [[CiteRef::Uzgalis (2016)|p. 4]] Locke's most important contribution to this argument was his ''An Essay Concerning Human Understanding'', published in 1689. Locke and Newton became directly acquainted while Locke was finishing this work. When Locke read Newton's ''Philosophiae Naturalis Principia Mathematica'', published in 1687, he found epistemological views similar to his own. Both had absorbed the views current in the Royal Society. Locke's essay received its warmest reception from the members of the society, and can be deemed an expression of their collective understanding of scientific methodology. [[CiteRef::Rogers (1982)]]
|Major Contributions==== Locke's Empiricism ===
In the first book of his ''Essay Concerning Human Understanding'' Locke begins by arguing that there are no principles or ideas that are innate in human beings. In seventeenth century England, such principles were widely held to exist and to be necessary to the stability of religion and morality. [[CiteRef::Uzgalis (2016)]] "Nothing is more commonly taken for granted" he wrote, "than that certain principles both speculative and practical are accepted by all mankind. Some people have argued that because these principles are (they think) universally accepted, they must have been stamped into the souls of men from the outset." [[CiteRef::Locke (2015a)|p. 3]] He denies that we hold speculative innate principles, including innate ideas of God, identity, or impossibility. If This criticism was aimed widely, but was directed, in part, at Cartesians, who held, among other things, that we have an innate idea of substance. [[CiteRef::Rogers (1982)]] Locke maintained that if there were such innate principles, he supposes, they would be known to everyone, even "children, idiots, savages, and illiterate people", which was clearly not the case. [[CiteRef::Locke (2015a)|p. 8]] Mathematical truths likewise cannot be innate, as these must be discovered by reason and are learned from others by most people. [[CiteRef::Uzgalis (2016)]]
In the second book, Locke begins his positive account of how people acquire knowledge. "Let us suppose", he writes, "the mind to have no ideas in it, to be like ''white paper'' with nothing written on it. How then does it come to be written on?...To this I answer, in one word, from ''experience''". Locke's belief that all knowledge comes from sense experience is '''empiricism'''.[[CiteRef::Locke (2015b)|p. 18]] Unlike Descartes, Locke does not seriously entertain the possibility that his senses are fundamentally unreliable. He writes that, "We certainly find that pleasure or pain follows upon the application to us of certain objects whose existence we perceive (or dream we perceive!) through our senses; and this certainly is as great as we need for practical purposes, which are the only purposes we ought to have". [[CiteRef::Locke (2015d)|p. 202]] When our senses are applied to particular perceptible objects, they convey into the mind perceptions of those things. This '''sensation''' is the source of most of our ideas. We can also perceive the workings of our own mind within us, which gives us ideas of the mind's own operations such as "perception, thinking, doubting, believing, reasoning, knowing, willing, and all the different things our minds do", a process which Locke calls '''reflection'''. [[CiteRef::Locke (2015b)|p. 18]] Simple ideas produced by these processes can be grouped into complex ideas, such as those of substances and modes. '''Substances''' are independently existing things like God, angels, humans, animals, plants, and constructed things. '''Modes''' are dependently existing things like mathematical and moral ideas, which form the content of religion, politics, and culture. Note that while Locke does not believe that we are born with ideas, he believes we are born with faculties to receive and manipulate them. [[CiteRef::Uzgalis (2016)]]
