You foolishly claimed that it could be formalized using only propositional logic (with no predicates or quantifiers). Must be frustrating as hell for you.

[snip]

"It was raining in the past. (fact?)
x in N & Today(x) & EXISTS(y):[ y in N & y<x & Rain(y)]

> And that this is fiction:
> "It will rain tomorrow."
> Today(x) & Rain(x+1)

"It will rain in the future" (fiction?)
x in N & Today(x) & EXISTS(y):[ y in N & x<y & Rain(y)]
