Philosophize means:
* To engage in philosophical thought or discussion. This can involve examining fundamental questions about existence, knowledge, values, and reality.
* To apply philosophical principles to a particular situation or problem. This involves using reason and logic to analyze and understand a situation, and potentially to arrive at a solution.
So, instead of "philosify," you'd use "philosophize" in a sentence like:
* "We spent the evening philosophizing about the meaning of life."
* "The professor encouraged us to philosophize about the implications of the scientific discovery."
