formulations of the categorical imperative are discussed. It is true that Kant stated the categorical
imperative in many ways, however, the categorical imperative is only one thing. It is how we must
always act. Three of the ways in which Kant formulated this are exposited, however, Kant was
expressing the same idea each time, in three different ways; much the same as we might say
something in three different ways in our ordinary daily life. Let’s say, for example, that someone is
going to do some gardening in their backyard — someone might say, “I’m going to do some gardening
in my backyard” or, “I’m going to work a little bit in the garden” or, “I’m going to do some work on
the landscaping.” In each case, they feel they are saying exactly the same thing; they do not feel that
they are saying three different things. Kant, in formulating the categorical imperative, always believes
himself to be giving the same rule of action; he was merely using different words to express his
concept. However, many commentators will treat each of these formulations as if it is distinct. The
three formulations which Bowie speaks of and which most commentators focus on are: 1) “act only
on maxims which you can will to be universal laws of nature” 2) “always treat the humanity in a
person as an end, and never as a means merely” and 3) “act as if you were a member of an ideal
kingdom of ends in which you were both subject and sovereign at the same time.”
A quick examination of each of these formulations should indicate to us that they are essentially the
same thing. Let’s start in the middle and work our way to either end from the middle formulation. The
middle formulation is given as “always treat the humanity in a person as an end, and never as a means
merely” (linguistically, you may find it easier to work with the construction “always treat the
humanity in a person as an end, and never merely as a means”). If we do that, then naturally the first
formulation — that we should act only on rules which we can will to serve as a universal law of
nature, necessarily follows. For example, if I’m always treating each person as an end with the utmost
respect for their humanity, then naturally, whatever rules I use in my interactions with them I would
wish to be uniform and universal — and I would want them to be applied to me by an actor as well as
be applied by me to a subject. Similarly, treating the humanity in a person as an end and never as a
means really is the same as if I am in an ideal state or ideal society and I can imagine myself both to
be the ruler of this society and a citizen of the same society. The society’s rules would naturally
reflect the humanity of each and every subject because essentially what I formulate in my mind when
I am playing both roles (sovereign and subject) is certainly not going to take advantage of the
citizenry, since I am also a citizen.
Nonetheless, Bowie does discuss each formulation, at least moderately, as if it is something different.
Bowie uses as an example a situation where he thinks Kant would have difficulty. Kant really says
that if you want to have effective promises, you cannot say it is ever permissible to allow promises to
count for nothing, since no one would know which promises were true and which were false and
therefore, no one would ever trust promises at all. Yet following through with that example, almost
every company has experienced a situation where the terms of a contract are not lived up to 100%.
This is taken by Bowie to mean that Kant would therefore say that contracts would become worthless
because companies could not trust them. What Kant is saying, though, is not that the breaking of
contractual promises does not happen, but that if it always (or perhaps with some certain degree of
regularity) happened it would prevent the activity of contracting. Bowie then backtracks a little bit
and talks about situations in which businesses modify how they behave based on how they are treated,
which is possibly more in line with what Kant would say.
Bowie treats the next conception of the categorical imperative “always treat the humanity in a person
as an end, and never as a means merely” by identifying persons with stakeholders.
