∃x (P(x) ∧ ¬Q(x))

Formal logic is the grammar of thought. Each symbol is precise. Each statement is either true or false. There is clarity here — and beauty.
Daily Practice
Logic is not a talent. It is a practice. Every day, examine one argument. Identify its premises. Trace its inferences. Test its conclusion. This is ronri.day — the daily discipline of clear thinking.
