Error al insertar en la base de datos SQL usando PHP

Tengo un programa con una consulta de inserción MySQL:

        $sql = "INSERT INTO people (person_id, name, username, password, email, salt)
                VALUES ($person_id, $name, $username, $password, $email, $salt)";
        if ($con->query($sql) === TRUE) {
            successful();
        } else {
            unsuccessful("Error: " . $sql . "<br>" . $con->error);
        }

Cuando ejecuto el código me sale este error:

Error: INSERT INTO people (person_id, name, username, password, email, salt) VALUES (2, Tom Jack, tjack95, 8a01fc598a676a249c5844bd3baf4f4d83cecdf2, [email protected], eb694539989fda2e17f79e70fb306f8911c3dee5)
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Jack, tjack95, 8a01fc598a676a249c5844bd3baf4f4d83cecdf2, [email protected], eb69' at line 2

El inserto sql me parece completamente bien. ¿Cuál es el problema?
