A simultaneous semantical and syntactical reduction is given for the satisfiability respectively finite satisfiability of first order formulas. We choose ∀∃∀∞(0, 1) as conservative reduction class and allow only formulas out of ∀∃∀∞(0, 1) having a simple set theoretical model if they are satisfiable at all. With the same method we get a spectral representation of any ϱ‐ary enumerable respectively coenumerable predicate by a formula out of ∀∃∀∞(ϱ, 1).
