I said just now
I see no objection to
I see no reason to doubt
I shall ask you one question
I shall attempt to show
I shall content myself with asking
I shall not suffer myself to
I shall not undertake
I shall presently show
I shall sum up what has been said. 
I shall, then, merely sum up
I share the conviction of
I should hold myself obliged to
I should not like to hold the opinion
I speak in the most perfect honesty
I speak only for myself. 
I suppose most men will recollect
I take leave to say
I take the liberty of
I think I am right in saying
I think I can demonstrate that
I think it impossible that
I think it our duty
I think it well not to be disputed that
I think, on the contrary, that
I think that this is a great mistake. 
I think these facts show that
I think we should be willing to
I trust it will not he considered ungenerous
I trust we are not the men to
I turn now to another reason why
I undertake to say
I use the word advisedly. 
I venture to assert that
I venture to say
I venture to think
I want to invite your attention to
I want to know whether
I was astonished to learn
I was forcibly struck with one remark
I was very much struck with
I will allow more than this readily. 
I will answer, not by retort, but by
I will call to mind this
I will go no further
I will not attempt to note the
I will not enter into details
I will not go into the evidence of
I will not stop to inquire whether
I will show you presently
I will speak but a word or two more. 
I will suppose the objection urged
I wish I could state
I wish to call your attention to
I wish to know
I wish to say something about
I wish to observe that
I would not he understood as saying
I would not, indeed, say a word to extenuate
If any man were to tell me
If any one is so short-sighted
If I had my share
If I hesitate, it is because
If I insist on this point here
If I mistake not the sentiment of
If I must give an instance of this
If I read the signs of the time aright
If I were asked what it is that
If other evidence be wanting
If, perchance, one should say
If such a thing were possible
If such feelings were ever entertained
If such is the fact, then
If there is a man here
If we accept at all the argument
If we are conscious of
If we find that
If we resign ourselves to facts
If you want to find out what
If you wish the most conclusive proof
In a broader and a larger sense
In a sense, and a very real sense
In answer to this singular theory
In like manner
In order to carry out
In proof of this drift toward
In proportion as
In proportion, then,
In pursuance of these clear and express
In saying all this, I do not forget
In something of a parallel
