"reduce" is a verb so to "reduce mathematics to logic" means to do some action,
You are making a statement that at best is true or false. That statement is not doing something.
And how is "logical discourse" quantified? Is the statement, "For all mathematical discourses, there is a logical discourse in which it can be interpreted."?
What have you done that constitutes the action of "reducing"?
