An ignostick is a hypothetical object used in discussions about the nature of beliefs and the existence of deities. It is defined as a stick whose properties and characteristics are so vague or undefined that it is impossible to engage in meaningful discourse about it. The term often serves to illustrate the concept of ignosticism, which posits that certain questions about the existence of God are meaningless if the terms involved are not clearly defined. In essence, it highlights the importance of clarity in philosophical and theological discussions.
