For example, at first it seems obvious to the Talmud that if one wanted to throw something eight amot in the public area (amot means elbows), and threw only four amot, then it is the same as if one wanted to write the name Shimon, and wrote only Shem, which is also a name, then he has violated Shabbat.
Many things require explanation here. What is a public area? That is similar to the Temple building site, which is visited by 600,000 people daily and has no roof or walls. And where did they throw objects when building the Temple? That is what they did with construction materials. And what is the size of the public area? - Sixteen amot, just as the size of the construction site that could fit the carriages used by the Levites.
But later, the Talmud changes its mind about what it thought was obvious. It has to define "carrying" or "throwing" as a sequence of two acts: picking up the object in one place and then letting it land in another. With this definition of carrying, logic becomes much clearer.
