Certainly! Let's consider the following philosophical argument as an example. We will use symbolic logic notation to represent the concepts and their relationships. 

Let's define the following symbols:
1. F: "Free will exists."
2. D: "Determinism is true."
3. R: "Moral responsibility exists."

Here's an argument:

Premise 1: D → ¬F (If determinism is true, then free will does not exist.)
Premise 2: ¬D v F (Either determinism is not true, or free will exists; this is the logical negation of Premise 1)
Premise 3: R → F (If moral responsibility exists, then free will exists.)
Premise 4: R (Moral responsibility exists.)

Now, let's derive the conclusion:

Step 1: R (From Premise 4)
Step 2: R → F (From Premise 3)
Step 3: F (From Step 1 and Step 2 using Modus Ponens)

Conclusion: Free will exists.

In this example, the argument supports the existence of free will (F) based on the assumption that moral responsibility (R) exists. It also assumes that if moral responsibility exists, then free will must also exist (Premise 3). Additionally, it considers the concept of determinism (D) but provides us with logical possibilities that either determinism does not exist or free will exists (Premise 2). Ultimately, the conclusion reached is that free will exists (F).

While it's challenging to present a complete philosophical argument for the existence of free will using a single formula in symbolic logic notation, here's a simplified example that outlines one possible approach:

Let's assume the following basic premises:

1. Necessitarianism: All events, including human actions, are determined by prior causes (denoted as ∀x(Cx → Ex), where "Cx" represents the set of prior causes of event "x," and "Ex" represents the occurrence of event "x").
2. Compatibilism: Free will is compatible with determinism (denoted as FW ∧ DET, where "FW" represents the existence of free will, and "DET" represents determinism).

To support the existence of free will within this framework, we can construct a modal syllogism using the following formula:

(1) ∀x(Cx → Ex) (Premise: Necessitarianism)
(2) FW ∧ (∀x(Cx → Ex) → □(Ex ∨ ~Ex)) (Premise: Compatibilism)
(3) □(FW → (∃x)(Cx & (Ex ∧ ~□Ex))) (Conclusion: Existence of free choices)

Here's a breakdown of each formula:

1. This formula states that for every event "x," its occurrence is necessarily caused by prior causes (∀x(Cx → Ex)).
2. Compatibilism asserts that the existence of free will (FW) is consistent with determinism (DET), and that if determinism holds (∀x(Cx → Ex)), then every event "x" is either necessarily determined (□Ex) or its negation (~Ex) is necessary (∧-operator).
3. This conclusion follows from (1) and (2) using the modal operator "□" (necessity) and the existential quantifier (∃x). It states that if free will exists (FW) and determinism holds (∀x(Cx → Ex)), then there must exist at least one event "x" that is caused by prior conditions (Cx) and has a free choice (Ex) that is not necessarily determined (~□Ex). This implies that the agent has the ability to make choices that are not predetermined by prior causes, thus supporting the existence of free will.

Note that this argument assumes a specific interpretation of free will and determinism, and it's not a complete philosophical argument, as it doesn't address all potential objections or counterarguments. Nonetheless, it provides a glimpse into how symbolic logic notation can be used to structure and express philosophical arguments about free will.

Suppose a person/person A commits an action/x and another person/person B is able to conclude that A in some way caused B, thereby implying that person A had control over their action, i.e. A had free will. This can be represented as (A caused B) → (A had free will). This argument is supported by symbolic logic in a circular manner, as it assumes the premise that person A had free will in order to make the argument that person A caused something. However, this circular reasoning is necessary, as it implies that person B had some way of determining that person A had control over their own action, otherwise the argument would be incomplete.
