I couldn’t make any judgment on the Summa, except to say this: I read it every night before I go to bed. If my mother were to come in during the process and say, ‘Turn off that light. It’s late,’ I, with lifted finger and broad bland beatific expression, would reply, ‘On the contrary, I answer that the light, being eternal and limitless, cannot be turned off. Shut your eyes,’ or some such thing. In any case I feel I can personally guarantee that St. Thomas loved God because for the life of me I cannot help loving St. Thomas.
