Student or Learner
Please help me understand the following in bold.
As I have often said, some of the greatest truths in life are the simplest. For that reason, I generally speak and write at the seventh-grade, third-month level. I've also found that if I keep it at this level, even college professors will be able to keep up with me. But Dr. Steve Franklin says, "The great truths in life are the simple ones. You don't need three moving parts or four syllables for something to be significant."
In the above, does "keep up with me" mean "understand what I'm saying?" If so, it sounds strange. If the writer speaks or writes at the seventh-grade, third-month level, wouldn't it be very easy to understand? However, the writer says if I keep at this level, even college professors will be able to "understand what I'm saying." It seems a strange logic.
And what's the meaning of "moving parts"?
