Fundimentally, when you talk about a if statement, you are talking about the ability to do something different dependent upon some state.

It's the same thing as stimulus, response.

Unchanging in response to circumstances is static.

Changing in the absence of circumstances is randomness.

The conditional is all that remains. Changing in response to circumstances

(Arguably, unchanging in the absence of circumstances completes the truth table, but it's a whole lot of nothing)
