Causality
Some interpretations in physics dispense with causality; in that these interpretations are no longer scientific, since science is nothing but the investigation of causality, of why things are as they are. Physics without causality is no longer science, but mysticism. Believing something to be as it is without needing any explanation in physics is as unscientific as believing this in religion. Scientists who say that the occurrence of a physical event needs no cause are no better than creationists who say that the existence of God needs no cause, and surely polytheists believed the same in the past about their gods; but we only give up finding the cause of something and say that it "just is" when we are confused about it. Some things about modern physics are very confusing, but that does not give us an excuse to descend into despair to explain them.

Determinism
Determinism is a most natural consequence of causality, as anything that is not deterministic has no cause. Determinism is causality. If something is purely "random," like the position of a quantum particle, this means it has no real cause.
The uncertainty principle therefore has an inherent flaw.
If everything has a cause, then, in theory everything can be predicted.

Multiple Causality
Nothing in nature has only a single cause; it almost always has several causes. Scientists sometimes argue about what the cause of something is -- they're all right to some extent, except in believing their cause is the only cause. This is so for pretty much all multiplex systems from quantum physics to evolution, in none more so than in our own minds: it is therefore unsurprising that every form of psychotherapy, each concentrating on a different cause, is equally (in)effective.
