# From the measurement problem to the primitive ontology programme

## TL;DR

This paper traces the evolution from the quantum measurement problem to the primitive ontology programme, analyzing the contributions of GRW theory and comparing different ontologies like GRWm, GRWf, and Bohmian particles.

## Contribution

It provides a comparative evaluation of various primitive ontologies in quantum physics, focusing on GRWm, GRWf, and Bohmian ontologies.

## Key findings

- GRWm offers a matter density ontology with specific advantages and disadvantages.
- GRWf proposes a flash ontology with distinct conceptual implications.
- The paper assesses the strengths and weaknesses of each primitive ontology in explaining quantum phenomena.

## Abstract

The paper retraces the development from the measurement problem to the primitive ontology programme. It assesses the contribution of the GRW theory to this programme and discusses the pros and cons of the GRWm matter density ontology and the GRWf flash ontology in comparison to the Bohmian particle ontology. It thereby pursues the evaluation of the proposals for a primitive ontology of quantum physics.
