Why do they gravitate?

Yes, his general meaning is understood.
The force concept arises out of a deep-seated need for a causal explanation of physical interactions. It's like a trap. The causal models are psychological and forms of reductionism. Larson was not immune to this trap either. In his version of scalar motion, space and time are indeed "causal" as well when space and time are considered seperately as aspects of motion. This reductionism expressed in the discrete unit postulate.
However, the universe is inherently less reduced, being both causal and acausal. Psychologically, the quality of space is causal, and the quality of time is acausal. But since space = time, both can also always be expressed in terms of each other. That is, time can be conceptualized as being causal. However, in order for us to conceptualize a causal aspect of motion (be it space or time), the other aspect, when considered simultaneously, then becomes conceptually acausal.
It should be kept in mind that I am talking about the psychological conceptualization of motion, not the pure mathematical abstraction of motion. But I think it bears some consideration because physical theories rely on conceptualizations to be understood and accepted.
Another way of expressing causality and acausality is with the concept of differentiation (or seperating) and integration (or connecting).
