It is not enough to say

It is not entirely clear to me

It is not evident

It is not for me on this occasion

It is not given to many men

It is not likely that any of you

It is not logical to say

It is not my intention to enter into

It is not my purpose to discuss

It is not necessarily true

It is not necessary for me even to sketch

It is not necessary for our purpose

It is not often in these modern days

It is not ours to pronounce

It is not out of place to remind you

It is not possible to recount

It is not quite clear

It is not to me so very surprising

It is not too much to say

It is not unknown to you

It is not within the scope of this address

It is now high time for me

It is now perfectly plain

It is observable enough

It is obvious

It is of course difficult

It is of great importance to show

It is of no moment

It is of very little importance

It is often remarked

It is on these grounds

It is one of the burning questions of the day

It is one of the most natural visions

It is one of the most significant things

It is one of the queerest freaks of fate

It is only a few short years since

It is only just to say

It is our duty to examine

It is ours to bear witness

It is owing to this truth

It is peculiarly befitting at this time

It is perfectly apparent

It is pitiable to reflect

It is pleasant to meet this brilliant company

It is rather a pleasant coincidence

It is rather an arduous task

It is rather startling

It is related

It is ridiculous to say

It is said, and I think said truly

It is said to be impossible

It is satisfactory to notice

It is scarcely necessary to insist

It is scarcely questioned

It is self-evident

It is sometimes hard to determine

It is still an open question

It is still more surprising

It is substantially true

It is surely necessary for me

It is the clear duty of

It is the doctrine of

It is the fashion to extol

It is the universal testimony

It is therefore evident

It is therefore necessary

It is this which lies at the foundation

It is to be expected

It is to be remembered

It is to me a very sincere satisfaction

It is told traditionally

It is too plain to be argued

It is true

It is unnecessary for me to remind you
