No, that's an a priori concept. A posteriori concepts comprise empirical knowledge which necessitates experience of the world [1].
Example: you can know a priori that "all bachelors are unmarried." If I tell you "Tom is a bachelor" then you know that Tom is unmarried (assuming I tell the truth about Tom being a bachelor).
But if I say "all bachelors are unhappy" then you haven't learned anything because knowledge about the happiness/unhappiness of bachelors is an empirical question. To know whether or not I was telling the truth, you would need to conduct research about the real world, for example by conducting a survey of bachelors.
