For example, the argument that If I had just sat on a wild porcupine then I would know it is probably not a fallacy and depends entirely on the truth of the leading proposition (the ability to know it).
Napríklad: argument, že Ak som si práve sadol na dikobraza, potom by som to mal vedieť pravdepodobne nie je klam a závisí výhradne na pravdivosti úvodného tvrdenia (schopnosti to vedieť).
