That's a really interesting question right now. We are just emerging from a period when the extremely dominant explanation was genetic....but are now moving back to a more nuanced analysis where genes and circumstances combine....
Also depends on what you mean by "mental illness". Are you speaking of Axis 1 diagnoses, like schizophrenia, bi-polar and the like?
If so, as far as I know, the genetics are looking crucial, and the discussion is about whether negative life circumstances may have a role in whether the gene is expressed, and to what extent it is expressed.
With personality disorders, there seem to be some who believe they are purely genetic, but I see very little good evidence of that, and I am mainly seeing that position taken in the US...which has a real dominance of medicalisation of pretty much everything, or so it seems from here.
Epigenetics and the increasing evidence of brain plasticity are also shaking up the debate.
I'm with Robert...I think both...with a preponderance or absolute of dominance of one or the other in some cases.
Maybe it's an acrequirement.
