For your kind information, Psychology is not an empirical science.
I suppose that depends on whether you are talking about clinical psychology (and other forms of counseling), or about research psychology.
Although research psychology doesn't often make the dramatic breakthroughs we have seen in physical sciences, it is nevertheless an empirical science.
As for clinical psychology, it seems that just about anyone can hang out a shingle declaring themselves to offer psychological counseling, so it is harder to say to what extent empirical science is involved.
Yes, Psychologists do not believe in the spirit.
That seems a broad generalization, particularly if you are including clinicial psychologists in the class you refer to.
