Editing Elemental theory of logic, we can believe

Elemental theory of logic, we can believe

point :
    1⃣ we use logic to certificate theory True or False
    2⃣ if logic is not common Truth, we cant share outcome of certification
    3⃣ then we cant doubt logic, that use to certificate True or False

what kind of logic & meaning, that use to certificate True or False ?

    1⃣ [[ And, or, in our certification ]]
    2⃣ [[ True & false ]]
    3⃣ [[ if (hypothesis) ]]
    4⃣ [[ then ]]

    writer recommend not to read 1⃣2⃣3⃣4⃣ because we know that. 
    we can trust 1⃣2⃣3⃣4⃣ = Elemental theory of logic,
    because we cant deny logic if logic not exist.
