Abstract

This chapter first talks about LEGO modal epistemology. Modal epistemology has the two parts. Some of it is the study of how one knows that some things are contingent and others necessary. The other part of modal epistemology concerns how much one know about what is contingent and necessary. The chapter then talks about what went wrong with the imagination‐based story. Whatever the story about how one knows what he/she can build, it had better be one that factors in his/her background knowledge, since that is what makes the imagination useful. With working knowledge of those little pieces, one can make judgments about what can and can not be done with them. Crucially, there are various ways to make those judgments. The chapter further focuses on a segment of the LEGO community that might seem a bit fussy: purists.
