Far from missing something, you appear to be seeing things that aren't there.
Let's go through this.
Nico wrote among other things:
...but it was specifically this portion of his post that I commented on.a) "be committed to doing sth" refers to energy, effort and time binding one to an ongoing activity, one that is already in progress;
b) "be committed to do sth" or "have a commitment to do sth" refers to a binding promise (can a promise be anythng but binding, I wonder?!) to do sth, to achieve sth not yet begun, only just outlined or proposed, to seek an outcome.
Let me know what you think! (There's more to come!!)
Now Nico's comment marked a) corresponds exactly with my comment a); and Nico's comment b) corresponds exactly with my comment b).I replied,
I also think that there is a significant difference between the two forms, however, I would like to slightly alter your definitions.
a) When followed by the gerund, it means that the subject promises and binds themselves to carrying out the activity. I think that the activity does indeed need to be already on-going.
b) When followed by to and the infinitive, it implies that the committment is imposed externally, either because it has been mutually agreed and the subject feels beholden to the promise, or because it has been imposed by judicial authority. For instance, a judge might sentence someone saying, "I commit you to ten years hard labour." Thus the promise or the judicial authority are the external imposition.
I shall add this to my Venn diagram. There's more to come you say, ready when you are.
In a) Nico writes, "be committed to doing sth" but "I write when followed by the gerund" now maybe I'm missing something here, but isn't "doing" a gerund?
In b) Nico writes, "be committed to do sth" or "have a commitment to do sth", I refer to "to" and the infinitive ("to do" is "to" and the infinitive.) I go on to explain what I feel is the difference in meaning more clearly between to and the infinitive and the gerund. I did not distinguish between the two forms of the infinitive here, there are differences, but I think my analysis still holds. I agree that "committed" can be construed as an adjective (or as a past participle), but it was Nico who introduced this, not me.
Both you, Duncan and Larry seem to think that I have tried to change or have accidently changed the form under examination
At no point in this post do I imply that something that I have written is the same as what Nico wrote unless it actually is the same. At no point in this discussion do I subtly or not so subtly change the form under examination. I really am not following you here, Duncan.the form under examination gets subtly (or not so subtly!) altered in the course of discussions
