Did the Apostle Paul believe in the immortality of the soul?

The Apostle Paul used to be a Pharisee at one point, and Pharisees believed in the immortality of the soul [citationneeded], but then Paul became a Christian through a dramatic conversion, and I don't know to what extent his beliefs on the afterlife might have changed. Did the Apostle Paul believe in the immortality of the soul? Can this question be answered objectively to any extent (on the basis of objective evidence)? Is there consensus among scholars and historians on this topic? ______________ **Note**: Is this an "obvious" question? At first glance it might look so for many, but once you have garnered some experience exchanging thoughts with [Christian mortalists](https://en.wikipedia.org/wiki/Christian_mortalism) and [Annihilationists](https://en.wikipedia.org/wiki/Annihilationism) (e.g. see [here](https://hermeneutics.stackexchange.com/q/27088/38524) & [here](https://hermeneutics.stackexchange.com/q/73790/38524)) , the answer to the question no longer looks so "obvious". _____ Related BHSE question: [What are the theological implications of Paul's continuing identifying himself as a Pharisee in Acts 23:6-10 despite being an Apostle of Christ?](https://hermeneutics.stackexchange.com/q/74210/38524)
