Use or omission of articles [duplicate]

In the introduction of my thesis, I have the following statement: "It has been stated [...] from both __ theoretical and __ experimental standpoints.".

My advisor is saying that I should put indefinite articles ("a" and "an", respectively) in the blanks. However, I don't think any articles are necessary, and it even sounds better without them. A reasonable middle ground for me seems to put a "the" in the first blank only. Are any of these options correct? If so, which are better sounding?

Solution 1:

After quite a bit of searching on the Corpus of Contemporary American English and google books, I would say that the version where neither coordinate has an article is the most common by a sizeable margin.

Having said that, in published literature we find almost all possible combinations (except those where the first coordinate doesn't have an article, but the second does), and usually I can't find any obvious reason why the author chose the combination they chose. The rarest is the mixed case, where one article is indefinite and the other definite, but I have been able to find an attested example even of that.

In the examples below, if no source is explicitly given, then the example comes from the Corpus of Contemporary American English (COCA), with the restriction that the source has to be academic.

Solution 2:

The indefinite article is inconsistent between singular and plural. It can only be used with a singular noun.

I can see a dog running towards me.

But

I can see dogs (or some dogs) running towards me

So the omission of the article is correct. Your case is more complicated because you have two adjectives (theoretical and experimental) qualifying the same noun (standpoint).

You have done exactly the right thing in putting that noun in the plural and not using indefinite article.

You could use an, but in that case you would use the singular standpoint. so

... from a theoretical and an experimental standpoint.

The noun is now singular because what you have is short for:

... from a theoretical standpoint and an experimental standpoint.

You could even use 'from' twice,though that makes the it more cumbersome.
