Full Idea
Simons's 'nuclear' option blends features of the substratum and bundle theories. First we have tropes collected by virtue of their internal relations, forming the essential kernel or nucleus. This nucleus then bears the non-essential tropes.
Gist of Idea
Internal relations combine some tropes into a nucleus, which bears the non-essential tropes
