I define philosophy as "the rational and rigorous pursuit of what is true and right". In other words, I see it as process,
rather than as content. As such, discussions on all topics are welcome, so long as the rational and rigorous approach is adopted.
However, I have one "taboo" topic: Singapore. There are lots of other forums for this.
The guidelines are simple. Besides being rational and rigorous, do keep your contributions short, simple, relevant
