Yes, although you might get an argument against defining psychology as a science.

My neighbor, as a christian-type philosopher, always criticizes science for its inability to "answer the big questions". (Of course, he primarily wants to fight over the 'truth' of evolution.) But, imo, science isn't really set up to handle those big philosophical questions. In their hubris, some scientists have attempted overall ideas, like the Big Bang theory, but all that is really based on philosophy and strays from what I think of as true science. Nothing wrong with these ideas, just label them as they are.
