Sorry for not explaining! FOLDS is an acronym for First Order Logic=20 with Dependent Sorts, with which I knew that Tom is familiar (having=20 discussed its pros and cons with him back when we were both students). > Google was not very helpful. Googling the whole phrase does produce satisfying results,=20 but to save you the effort, I can point you (all) towards http://www.math.mcgill.ca/makkai/folds/ Cheers, Jeff.
