No, she's wrong. The modern scientific models each form a kernel of truth from among the BS, and today we have to deal with quantum mechanics and its quirky bizarre predictions which invalidate the "just look at it" and "just think about it" schools of philosophical thought.
For example, she claims that God exists. A typical trait of God is knowing everything about the universe; say, knowing the positions, momenta, and spin of every particle. But QM gives us Heisenberg's Uncertainty, which prevents anybody, including hypothetical deities, from knowing that information. Indeed, QM typically isn't materialistic; it is wrong to insist that all of those particles definitely have some position and momentum at an instant in time. So, whatever her God is, it isn't the all-powerful one. (The all-powerful God has many better-tread problems in pure metaphysics, like the Problem of Evil, but I don't know what "evil" is and so I'm leaning on QM.)
There is no problem in having to learn philosophy by reading surveys of historical ideologies. Philosophy is cumulative, and as little as one semester of studying historical philosophy can massively improve a person's critical thinking skills.
Really, the problem is in not taking seriously enough the invalidation of old philosophies by newer thoughts, as we continue to improve what we know. There are many positions that are simply wrong, including positions which we currently think are correct!
