Hume-Section XII- part 1 of the academical or sceptical philosophy

A little later into this section, Hume focuses on aspects of primary and secondary qualities. He says that universally man can detect secondary qualities right off the bat. When someone is asked, is this hard or soft? Is his black or white? Is this a triangle or circle? These ideas can be known by use of the senses. The mind perceives the qualites of these objects without knowing any other information. If someone draws a triangle and says what is this?, the answer will be a triangle (unless this person has never been introduced to a triangle before). Hume says, "...if it be a principle of reason, that all sensible qualities are in the mind, not in the object". That statement is very interresting. It is like someone made up a word, let's say soft. Then they said soft things can be described as fluffy, comfortable, nice, smooth or mushy. Then they said pillows are soft or cashmere is soft and then that idea stuck and has just been passed on until the present time. Let's just say instead of the word soft meaning all those words, hard is the word that means fluffy, comfortable, nice, smooth or mushy. Everything would be opposite. Soft and hard are just names tacked onto objects because somebody decided that is what those words mean.
