Entry #17: A Philosophical Lexicon for Perfumistas

Leibniz' Law


For any two things X and Y, X is equivalent to Y 
if and only if every property of X is a property of Y, 
and every property of Y is a property of X.

It might seem on its face that Leibniz' Law is being violated left and right in the age of reformulation. Nina Ricci L'Air du Temps is no longer L'Air du Temps, because the properties of the early and the more recent perfume bearing that same name are not one and the same. The ingredients have changed, in this particular case, a lot.

What's in a name? I discovered through an auto-Google that my given name is shared by several other people in the United States. I was surprised by this, as my name is not Jane Doe, and it seemed hard to believe that my first name would be attached to the same last name in so many other cases. But it was. As a result, multiple entities bearing no resemblance to me share my name.

The same can be said for sherapop, of course. Who is sherapop? Is she the princess of power? Or is she the philosopher of perfume? Or is she the philosopher of power? Or is she the princess of perfume?

All of these examples illustrate nothing really, because no one ever said that the same name could not be attached to two very different things. An interesting example in natural language is the string of letters g-i-f-t. Gift means present or wife or poison, depending on the language, and most people would consider those three to be very different things!

When a perfume company retains the name of a classic perfume for a less expensive or "re-imagined for the modern wearer" reformulation, have they violated Leibniz' Law? Not exactly, but they are banking (literally) on the fact that consumers will assume that the praise enjoyed by the earlier perfume is shared, transitively, as it were, by the newer perfume. 

In fact, the praise only applies or applied to the perfume actually sniffed, and when the two are dramatically different, then speaking of them as the same thing is rather like speaking of the very different people bearing my given name as one and the same, which is absurd. I do not deserve credit or blame for anything done by anyone else bearing my name. 

Names are crude bookkeeping devices, no more and no less, but they can be and are used by marketers to a company's advantage.

Entry #7: A Philosophical Lexicon for Perfumistas




Truth

In some ways, the concept of truth seems too obvious to bother discussing. In other ways, it seems too elusive to pin down, which can lead to the same conclusion: why bother?

Philosophers have spent a lot of time trying to understand what it means for a statement to be true. In logic, it's pretty straightforward. There are truth conditions on each type of logical statement. Let us consider one example, the conditional or hypothetical statement:


(1) If this perfume is a genuine Chanel perfume, 
then it was produced by the house of Chanel.

(2) If this perfume was produced by the house of Chanel, 
then it is a genuine Chanel perfume.


Which of these statements are true? These are conditional statements, readily recognizable by the if-then structure. If the first part (the antecedent or "if clause") of a conditional statement is true, then the second part (the consequent or "then clause") must be true in order for the statement as a whole to be true.

If the antecedent of a conditional statement is false, then the consequent could be either true or false, and the statement as a whole would still be true. In other words, the falsehood of the antecedent automatically guarantees the truth of the conditional statement. 



The two statements together express both a necessary and a sufficient condition: we can know that any genuine Chanel perfume was produced by the house of Chanel (not a knock-off operation), and any perfume produced by the house of Chanel is a genuine Chanel perfume. Because both of these statements are true, their conjunction is as well:

(1) & (2)


The truth conditions on a conjunction (joined by and or the ampersand) are simple. Both of the conjuncts must be true in order for the statement as a whole to be true. 

If all of this seems quite boring and trivial to you, that is probably because working out truth conditions on such logical statements is a far cry from talking about truths in reality. 

According to one theory of truth, the correspondence theory,  a true statement is one which corresponds to a state of affairs. We have an intuitive grasp of what truth is, but our criterion for denying that something is true is that it contradicts something else which we know or believe to be true.


Reformulation may on its face seem to be a good example. A perfume house may deny that they reformulated a perfume, and they may be telling the truth, or they may be lying, under the assumption that they have a right to say whatever they like about their own perfumes. 

If we examine the label of our bottle of Yves Saint Laurent Champagne, which was renamed as Yvresse, and compare the ingredients listed to recent bottles of Yvresse, we may conclude that the perfume is no longer the same. (This is only an example, and I hasten to add that I am not sure that Yves Saint Laurent has ever denied having reformulated its perfumes...)

It is possible, however, that labeling conventions have changed. You may have noticed that in the past many perfume bottles listed basically three ingredients:


Alcohol, fragrance (parfum), water. 

Not so anymore! These days, the list of ingredients goes on and on and on. So just finding that the labels read differently does not necessarily mean that the perfume was prepared using a different formula.




Sometimes houses simply contradict themselves. A recent example would seem to be Guerlain's announcement that they would be bringing Mitsouko back to its former glory. If they earlier claimed that the perfume was reformulated in order to comply with IFRA restrictions, then something has to give. Either it was never necessary to reformulate the perfume in the first place, or else it is impossible to bring Mitsouko back to its former glory, given the reigning IFRA restrictions, which have become more not less strict over the last few years.

The law of non-contradiction is key here. We reject the truth of a claim by showing that it is self-contradictory or implies something which we know to be false. The law of non-contradiction is the skeptic's most faithful ally, and the only inviolable principle. The skeptic may question every other statement ever made by anyone, but the basis of his rejection of some statements and theories is that something cannot both be and not be in the same way and at the same time.



Is reformulation a kind of self-contradiction? The answer to this question appears to be: No. Although we may bemoan reformulation (a few brave souls, going against the current trend, have argued that reformulations are often improvements!), it is not necessarily a contradiction for a company such as Coty to fob off a vastly inferior version of Muguet des Bois under the very same name as the perfume formerly known as Muguet des Bois.

It may be that, in the case of perfumery, the truth conditions are slightly different than we have come to believe in the case of most objects and things. The prevailing convention regarding naming of perfumes (given rampant reformulation) is that the company which produces a perfume gets to decide what goes in it, and they can change the ingredients at their caprice—for any reason whatsoever. 

The reason why people feel that they have been cheated when they buy a bottle of reformulated perfume going by the same name (and usually sold in the same type of bottle) as a cherished perfume is because they are assuming something akin to Leibniz' law:


Two things are identical if and only if all of their properties are the same.



In perfumery, the criteria are more lax: "Shalimar is Shalimar" just means that Shalimar is still created by Guerlain. That's it. They can pour whatever they like in the bottle and call it Shalimar, and their having done so is the necessary and sufficient condition for its being Shalimar, even though it may smell nothing like the original launch of that perfume.

When we feel cheated in a case of reformulation, it is because we have not fully appreciated that the house has the final say on its own creations. It's a godlike power, in a way. The house giveth and the house taketh away, and there is absolutely nothing that we consumers can do about it—beyond voting with our wallets. That is the extent of our power  in this realm.
