Theorizes

My friend Bratislav believes the Amerindian, Robert Morning Sky, who theorizes that creatures on other worlds will tend to evolve to have humanoid shape, as they approach sentience, be they apelike, lizard-like, insect-like, plant-like, fungus-like, etc.

My experience with diachronic ("through time") telepathy makes me believe that time may not be linear. One theorizes that psychonic or tachyonic particles or waves are faster than light, so that they can travel back in time. (Men like to explain away things, even if they do not understand fully. Women think that they need not understand how something works.)

He theorizes about political systems.
