Answer:
Yes. A personal philosophy of the meaning of life speaks to the tough questions, one of which could seek to establish the veracity of our beliefs.
"Where do we come from?"
"How do we know what happens after death?"
"What is the purpose of life?"
"How is it that the narratives about the origin of life are plagues with so much contention and controversies?"
The above are some examples of deep philosophical questions which deepen the knowledge we have about the meaning of life.
Cheers!
