&lt;br /&gt;
Many beginning students of [[intuitionistic linear logic]] are confused by the difference between [[multiplicative conjunction]] (&amp;amp;otimes;), [[additive conjunction]] (&amp;amp;amp;), and [[additive disjunction]] (&amp;amp;oplus;).  This may be because [[intuitionistic propositional logic]] features only two &amp;quot;combining&amp;quot; connectives, conjunction and disjunction.  The additional connectives arise from the linear nature of resources in linear logic and, specifically, the difference between internal and external choice.&lt;br /&gt;
&lt;br /&gt;
Suppose that Karl Marx has fifty dollars.  With that much money, Karl could buy a nice communist flag to wave, or he could buy a ticket to St. Petersburg, but he cannot do both --- for that, he would need one hundred dollars.  As a good party member, Karl is very frugal with the resources of the state!  There is a choice involved here, but where that choice is made can be important:&lt;br /&gt;
* If Karl makes the decision himself, this is said to be an ''external choice''.  Given the alternative, Karl can take the option he prefers.&lt;br /&gt;
* However, if Karl gives the money to Vladimir Ilyich to decide, then the result is an ''internal choice''.  Karl must be prepared for either a flag or a ticket;  he cannot predict which one he will get.  Choosing an alterantive at random, or following a procedure which is infeasible to completely analyze, are said to produce internal choices.&lt;br /&gt;
&lt;br /&gt;
An additive disjunction features an internal choice.  If Karl has the resource A &amp;amp;oplus; B, and Karl wishes to produce the resource C, then Karl must be able to produce C from whichever of A or B he receives.  However, to produce A &amp;amp;oplus; B, Karl must merely be able to produce one or the other.  For example, if Karl has a pear, Karl can produce (a pear &amp;amp;oplus; a stable capitalistic society) --- it's quite possible that an internal choice might feature something impossible!&lt;br /&gt;
&lt;br /&gt;
An additive conjunction features an external choice.  If Karl has the resource A &amp;amp;amp; B, and Karl wishes to produce the resource C, then Karl must be able to produce either C from A or C from B --- he can use whichever one is more convenient for him and the state.  However, to produce A &amp;amp;amp; B from some resources &amp;amp;Delta;, Karl must be able to produce A from &amp;amp;Delta; ''and'' he must be able to produce B from &amp;amp;Delta;.&lt;br /&gt;
&lt;br /&gt;
A multiplicative conjunction features no choice at all!  If Karl has the resource A &amp;amp;otimes; B, Karl has both resources at the same time, and he can use them both to good effect.  Of course, to produce A &amp;amp;otimes; B, Karl must be able to produce both simultaneously from the set of resources he has.&lt;br /&gt;
&lt;br /&gt;
Classical linear logic also includes a multiplicative disjunction, which captures the idea of having multiple resources which must be used separately;  this isn't really distinguishable from multiplicative conjunction in intuitionistic linear logic.&lt;br /&gt;
&lt;br /&gt;
== Apologia ==&lt;br /&gt;
&lt;br /&gt;
A crazed fool might wonder if this article is confused.  &amp;quot;Shouldn't&amp;quot;, such a simpleton might posit, &amp;quot;''external choice'' refer to additive disjunction?  After all, the choice is made ''externally'' to the user.&amp;quot;  This fallacy is, as fallacies are wont to be, wantonly, contemptibly, and even morally wrong.  The choice is internal to the disjunction, as its semantics are purely its own, and so this article's terminology is, if there were a god, which there isn't, as should be well understood by the reader, well in keeping with the divine plan.  No further comments will be entertaining.&lt;br /&gt;

&lt;div&gt;The [[KGB]] Kage is the place where we keep all of our [[hopes]] and [[dreams]]. It is our storage site and primary building location for [[Booth]]. &lt;br /&gt;
&lt;br /&gt;
The first Kage was located in the B sub-basement of [[Margaret Morrison]]. It was originally a simple, empty cage, unoccupied and unhappy. Then daring young [[KGB]] members came upon it, placed a luck upon its sacred door, and waited. When, after a year, they found the lock still thereupon, they christened the Kage and moved in. &lt;br /&gt;
&lt;br /&gt;
In the year 2003, the [[College of Fine Arts]], which controls [[Margaret Morrison]], lost its Design cluster to the children's school. As a result, they started to turn their attention to the lower basements, where the Kage, as well as other student organizations kept their stuff. The intrepid, fearless [[President]] of the [[KGB]] that year organized the other student leaders who controlled space in the basements of [[Margaret Morrison]] to resist the encroachment of [[CFA]], and was successful. However, as soon as that [[President]]'s tenure came to an end, and the negligent leadership of the following year took power, [[CFA]] swooped in and destroyed everything on the B sub-basement, including that glorious Kage.&lt;br /&gt;
&lt;br /&gt;
The Kage was then located in the C sub-basement, and it was a very nice Kage, with lots of headroom. The Kage had a sign above the door which, during booth season said, &amp;quot;Welcome!&amp;quot; During other seasons, the sign said, &amp;quot;Fuck off!&amp;quot; The Kage contains many wonders, but is now in a different place.&lt;br /&gt;
&lt;br /&gt;
In 2006, they finally got us to leave [[Margaret Morrison]], by giving us a room right under [[New House]]. There's much less headroom, but you can't beat the commute to [[Midway]].&lt;br /&gt;
&lt;br /&gt;
The Kage is entrusted to the keeping of the [[Sergeant at Arms]]. Any [[stuff]] that is collected for [[KGB]] should be given to the [[Sergeant at Arms]] for storage until such time as the revolution finds a use for it.&lt;/div&gt;</summary>
