My question is this: Is there a difference between logical and reasonable?
To me, logic is based on fact. To say that a decision was the logical choice, is saying that, by deduction, that choice was the correct one.
On the other hand, reason does not have to be logical per se. At least I don't think it does, perhaps that is where I'm wrong. To say that a decision was the reasonable choice is saying that perhaps that choice was not the logical one, but by presenting a valid argument, that makes the choice reasonable.
Although it seems like I just answered my own question, I don't think that I have because when I looked up logical on dictionary.com, one of the definitions was reasonable. (

Thoughts?
Actually, generally speaking, when you talk about a logical decision, you're not talking about deduction; you're talking about induction instead. Since 99% of our knowledge is based on induction, using logic is almost never going to be a pure form of deduction; since even when you deduce, your premises are questionable since they're the result of inductive logic. Unless all the universals you're using to deduce from are a priori, part of the whole of the thought process is going to be induction.
Por ejemplo, when I say "that ice cube over there is going to be cold", the actual thought is more like "there is an object a distance away from myself that I perceive to be an ice cube[inductive reasoning: all other objects that provide this set of stimuli have been ice cubes, therefore, this is also an ice cube]. From my experience, ice is always cold [and here's more induction], therefore the ice cube that I perceive will be cold."
Most of that is understood without the need to actually spell it out, I understand that is what is implied in the sentence "that ice cube over there is going to be cold."
The only time you're going to see a purely deductive thought is when the thought is an analytical a priori thought or a composite of synthetical a priori thoughts.
Of course, this has little bearing on your overall question, but I figured since we're talking semantics in the first place, we should be a little more precise in our definitions to avoid any confusion.
In summation, I agree with everyone else, reason and logic are, in a denotative sense in regards to philosophy, the same thing. In a more "common usage" denotative sense, I think you're right, reasonable can be a range of ideas broader than just the "perfect" logical idea. Drawing the line when using the word reasonable is your responsibility, I think, if you're going to be talking to a crowd of philosophers.
