"When I use a word," Humpty Dumpty said, in rather a scornful tone, "it means just what I choose it to mean—neither more nor less." "The question is," said Alice, "whether you can make words mean so many different things." "The question is," said Humpty Dumpty, "which is to be master—that's all."
-- Lewis Carroll, Through the Looking Glass
In my experience, if you can't say what you mean, you can never mean what you say. The details are everything.

Words, their meanings, their usages and implications are frequently the subject of arguments all their own, when dealing with the issue of beliefs and believers. With sufficiently indistinct or nebulous definitions, many theists will look for wiggle room or vagaries to avoid the ultimate meaninglessness of the belief system they stake so much on.
This situation has not escaped the attention of AronRa. In discussion and debate, he regularly spells out his terms and their meaning with specificity so well focused that many of his opponents may realize ahead of time that, referring to what Humpty Dumpty said above, he means to be the master of those words or at least declare the specific sense in which he uses them. I suspect that Aron has had to do this so often that he has many of these critical definitions memorized verbatim.
Back in 2012, Aron was good enough to record several of the most used terms involved in the discussion of matters religious and spiritual, along with his take on their meaning. The link above gives the full list; some of the more notable words and definitions follow:
I am nowhere near as facile as Aron is with these words, any more than I approach his skill at frustrating those who would test his depth of understanding of atheism and theism. Still, you know that old joke about how you get to Carnegie Hall, right?
Practice, practice, practice.
