There seem to be two different concepts:
a) Passive Voice: the grammatical construction
b) Passive Voice: a writers voice that happens to be passive
The prejudice against passive voice is usually based on b). But where things get confusing is that
the passive voice (a) is seen as a constituent of
a passive voice. And to compound the confusion, many don't seem aware of the style vs. grammar distinction they are using.
One thing I noticed is people using the indefinite article ("a passive voice") when talking about the grammatical concept ("the passive voice"). This is striking, because "a passive voice" is unusual in grammar texts (unless it's used un-hyphenated as an adjective: "a passive voice construction", "a passive voice sentence")
Example:
Here
To ensure you’re writing in an active voice, you need to understand the difference between active and passive verbs. With an active verb, the action in the verb is performed by the subject of the sentence. For example: The technical documentation finally met the expectations of managers. With a passive verb, the subject receives the action in the verb. For example: The expectations of the managers were finally met by the technical documentation.
There's nothing inherently wrong with this contains two concepts:
"Writing in an active/passive voice": Here "voice" seems to be a stylistic entity: something you can write in.
"active/passive verbs": i.e. verbs in
the active/passive voice.
So the assumption is that using verbs in the active or passive voice has stylistic consequences. When you are using a passive verb (i.e. a verb in the passive voice) you are writing in a passive voice (i.e. a voice, which happens to be passive). Now "voice" in Grammar and "voice" in stylistics are two different concepts. If you read the entire article, you'll notice that the author never uses the term "active voice"/"passive voice" in relation to verbs. She just calls them "active/passive verbs". Instead, "sentences are written in a passive voice". Note, that the sentences are not written in "the" passive voice.
My interpretation:
the passive voice (grammar) applied to a verb makes for
a passive voice (stylistics). But the difference isn't made clear. At least this article doesn't use the grammatical term as well (as other articles do).
There are more confused examples out there. No wonder new writers get confused, when there's such a mix-up of grammar and stylistics. Nobody wants to be accused of passive writing. (As an exercise, try to put that in the active voice so that it sounds better.) But, see, "the passive voice" doesn't necessarily make your writing passive.
This sounds like terminological nit-picking, but it isn't actually. Once you have the stylistic term "passive voice" (as in "writing in a passive voice") you can expand the concept to include other things than just the passive voice. There's an example in Plot Device's post. The sentence doesn't contain a verb in the passive voice, not in the grammatical sense. But it does contain a there-is construction; something that could also be counted towards a passive voice (in the specified stylistic sense).
A possible source for this misunderstanding is Strunk & White's
The Elements of Style, Rule 14, "Use the active voice". (Rule 11, in Stunks original booklet). Wikipedia has a link to an online version of S&W, which I'm not posting because I'm unsure about copyright status.
Strunk says that "Many a tame sentence of description or exposition can be made lively and emphatic by substituting a transitive in the active voice for some such perfunctory expression as there is or could be heard." (quoted in Selim's link as well.) Of the four examples that follow, only one has a verb in the passive voice. The other three examples are common to-be constructions (there was, it was not long before [he was], the reason that ... was). Does Strunk think these are passive voice? I don't think so.
Now it's time to remember what the rule is called: "Use the active voice". Is this synonymous with "Don't use the passive voice?" No, it isn't, and the three to-be examples show that.
Linking verbs are verbs that link subjects with a complement:
I am tired.
Green apples taste good.
There's a cat on the roof.
These sentences are neither in the active, nor in the passive voice. The rule "Use the active voice" makes sense here, if you understand it to mean: find a transitive verb (a verb that takes an object) to express the meaning you expressed with a linking verb and use it in the active voice. "Don't use the passive voice," makes no sense, here, whatsoever (grammatically speaking). There is no passive voice in these sentences.
However, thinking like this is quite complicated, and you'd have to know what a "transitive in the active voice" is
before reading that advice, to make sense of it (how many schools teach transitivity?). I wager most people will think that Strunk thinks that all these sentences contain a passive voice (even linguist Geoffrey K. Pullum - see Selim's link - thought so: 'This ... reveals the interesting fact that they seem to think existential clauses like "There is a spider in the bathtub" are in the passive voice.' I dislike
Elements of Style as much as Language Log does, but I do think Strunk's innocent of grammatical ignorance.)
So there are a couple of questions concerning
the passive voice in the context of
a passive voice:
1. Does the use of
the passive voice make a writer's voice "passive"?
2. Should writers avoid to write in
a passive voice?
3. Is
a passive voice defined onlyby including verbs in
the passive voice, or do we include other to-be constructions, and perhaps other language elements that have nothing to do with verbs?
4. a) Is the aversion to
the passive voice linked to the fear of victimisation? (Hey, nice things could happen to you! You could be given a present.)
b) Is the aversion to
a passive voice linked to the fear of boredom? (Is this circular? It's passive because it bores me, so if you write passive, you'll bore me.)
The passive voice itself is an essential part of the English Language and should be used. (Or would you advise people not to use the letter "x" because you don't like the spelling "thanx"?)
That's me with a long post about terminology, with little in it about writing.
