Read these lines from the excerpt again:

The minister gave out his text and droned along monotonously through an argument that was so prosy that many a head by and by began to nod„and yet it was an argument that dealt in limitless fire and brimstone and thinned the predestined elect down to a company so small as to be hardly worth the saving. Tom counted the pages of the sermon; after church he always knew how many pages there had been, but he seldom knew anything else about the discourse.

Based on the information provided in this excerpt, how would you characterize Tom?
