From my reading of Locke's work, the main ideas I gathered were as follows.
- Locke emphasizes that simple ideas come from elemental perceptions and are most nearly universal, whereas complex ideas are uncertain in nature, culture-bound, communal, or individual.
- Words represent ideas (as opposed to things), and theses words are ambiguous.
Our primary ideas, however, are identical. Here I must disagree.
I believe everyone's experiences are different, unique to that individual. Our perception of an experience affects how we feel about it and shapes our ideas. We use language to communicate these experiences and ideas in ways others can relate to, based on experiences and ideas of their own. If we all experienced everything exactly the same, what would be the need for descriptive language? From this reading I am uncertain if Locke actually did believe we experience things the same, but I feel his statement that primary ideas are identical lends itself to such a conclusion.
