I have found these sense-data and sensibilia. I have not made them. I do not know how to make them. I have not brought them together. […]
What holds them together? Why not ask first, “What separated them? What broke them up?” And the answer is, of course, “My analysis separated them and broke them up.” What holds them together? Why, they are together.[…]
What holds them together? Why, nothing. What holds them together? Why, everything. Canst thou lose the bonds of Orion? What holds together the sense-data of the apple? They are together. That is the way the apple is made; that is the way God made it grow.

This book outlines Luce’s version of Berkeley’s thought, which is similar but not identical, and uses the terms current rather than those used by Berkeley. As with Berkeley, Luce is attacking the philosophical (rather than common sense) view of matter. In this section he deals with the objection that sense-data such as the taste, smell, feel and appearance of an apple always appear together, so must be linked by matter.
