What does missiles of ligneous or petrous consistency have the potential of fracturing your caseous structure but appellations will eternally remain innocuous mean?

Answer 1

The phrase suggests that certain powerful or destructive forces (metaphorically represented by "missiles of ligneous or petrous consistency") can threaten to disrupt or damage your foundational beliefs or stability ("caseous structure"). However, despite these potential threats, the labels or names we use to describe these forces ("appellations") will always lack real harm or impact. Essentially, it highlights the contrast between the potential for damage and the relative harmlessness of mere words.
