Edwina,yes, "a human is a featherless biped" might be understood as singular description. I meant it as definition, so it is better to say "a human is defined as featherless biped", which is a proposition, a description of a status, and not yet a law. The semiosis of habit-formation goes 1-2-3, and the semiosis of reflexion the other way, so, yes, I agree, that it neither is correct that 2ns is more fundamental than 3ns, nor the other way. But I think logic is reflexion, so in this case 3ns (law, conclusion, the scroll) is primary to 2ns (actuality, proposition, nested ovals). With "more fundamental" I just was refering to the question in this thread about what is primary to what. I still am quibbling with the reason for intuitionalistic logic. But it is somwhat hard to show a primarity that cannot be illustrated with examples, as there is no loss or gain in meaning, merely a by me suspected academic rule, that logic is reflexion, and in reflexion 3ns comes before 2ns. But all in all I am merely suspecting and tentatively trying this and that.Best, HelmutHelmut - if you read Peirce's cosmological outlines [6.203 and 1.412], he begins with 1ns, moves on to the instantiations of 2ns, and then, into the developing habits of 3ns. So, the 'actualization' of the modes in spatiotemporal existence is linear.
But - all three modes are potential and necessary, therefore, I don't think that one can say that any one of them is 'more fundamental'.
And I'm not sure how a singular description of a variable [A human is a featherless biped] can be transformed into a sound deductive argument [IF it is a featherless biped THEN it is human]. As you point out, the connection of the attribute [featherless biped] might not always apply to the variable of 'human'.

Though the double negation´s meaning is the same as the conclusion´s meaning, the double negation has the form of a proposition, or a definition, which is secondness: "There is not a featherless biped that is not a human" may be classificationally instantated from exclusion of exclusion to definition: "A human is a featherless biped". The conclusion "If it is a featherless biped then it is a human" may be individually instantated to an argument; "It is a human because it is a featherless biped". It is thirdness, a rule or law. Which of both is more fundamental? Both mean the same, so if one changes, the other changes too. But which is more likely to change? The law "If it is a featherless biped then it is a human" cannot change just so, by itself. But the situation, the secondness, the truth of the proposition "There is not a featherless biped that is not a human" can easily change, and make the law obsolete, e.g. if an ape quits using its arms for walking, or if a dog sadly has two legs amputated, or if a chicken, due to a mutation, is born without feathers. So, is the double negation more fundamental, because it breaks the law? People will say, that the ape is just stupid, the chicken and the dog are just handicapped, exceptions only corrobate the rule, and all people who claim that the law is no longer in charge are heretics. A law (3ns) is more tenacious than actualities (2ns), that first have to prove worthwile one by one to add up to a certain measure, so is it more fundamental?Helmut
