Every effect has a cause: why would our decisions make an exception?

Supports

Everywhere we look, we find causes: on inspection, no phenomenon turns out to have no antecedent. The physical world appears , every effect within it having a cause that is itself physical.
A decision is one event among others, carried by a physical brain woven into that same causal fabric.
By the , nothing happens without a reason that determines it; to grant the will alone a causeless power would be an exception without justification.

Therefore Our decisions are therefore by their causes, like any other event.

Why would nothing happen without a cause?

The principle of sufficient reason states that, for every fact, there is a reason why it is so rather than otherwise.
To deny it is not to discover a freedom, it is to give up understanding: an event with no cause at all would be, literally, unintelligible.

Laplace's demon

Laplace imagines an intelligence that would know, at a given instant, all the forces of nature and the position of every being.
For such an intelligence, he writes, nothing would be uncertain: the future, like the past, would be present to its eyes.
The image is not about what we can predict, but about what strict determinism commits us to: everything, in principle, is already settled.
