In this article I do considerations regarding the applicability of equipollence criteria of Frege`s thought in relation to the peculiarities of natural language and in the cases of identity compounds thoughts. I intend to present and analyse the thoughts of equipollence criteria suggested by Frege in two Letters to Husserl and A brief survey of my logical doctrines. My first goal is to show that Frege presented an insufficient epistemic criteria and logical criteria appropriate to their goals. Then, I intend to test the applicability of logical criteria of equipollence before the rhetorical embellishment of natural languages and between the cases of identity thoughts present in article Compounds Thoughts. Thereby, my second goal is to expose what is the notion of consequence implicit logic in logical criteria of equipollence. In the end, I argue that the notion of consequence implicit logic in logical criteria of equipollence is not the formal notion of validity argument, but an intuitive notion of logical consequence.
