Ah, the fisticuffs in which intellectuals and spiritual adherents can indulge!
Each can point -- with aptness and/or venom -- to the failings of the other.
And yet the religion of the intellect and the well-tailored mental gymnastics of spiritual life both cry out and point to only one useful suggestion, as far as I can see:
The willingness to investigate honestly.
As Rumi suggested:
Out beyond ideas of wrongdoing and rightdoing.
there is a field. I'll meet you there.
