These absurd pretensions
They did what they could. 
This being the case, you will see
This brings me to a point on which
This does not mean
This expectation was disappointed. 
This I have already shown
This is a great mistake. 
This is it’s last resort. 
This is the only remaining alternative. 
This leads me to the question
This relieves me of the necessity of
This is clearly perceived by
This is especially true of
This is essentially a question of
This is very different from
Tho all this is obvious
Thus, you see
To avoid all possibility of being
To be sure
To-day I have additional satisfaction in
To my own mind,
To my own mind, certainly, it is
To pass from that I notice
To take a very different instance
To this end we must
To this, likewise, it may be added
To this there can be but one answer. 
To show all this is easy and certain. 
To show this in fact
To sum up, then
Truly, gentlemen

Unless I am wholly wrong
Unless I greatly mistake the temper

We all remember
We are all aware that
We are here to discuss
We are now able to determine
We are told that
We can not leave unchallenged the
We deny it. 
We have an instance in
We have no right to say
We, in our turn, must
We know they will not
We laugh to scorn the idea
We look around us
We may have an overpowering sense of

We ought, first of all, to note
We should pause to consider
We will hear much in these days
We will not examine the proof of
What are you asked to do? 
What are you going to do? 
What can be more intelligible than
What do you say to
What do we understand by
What has become of it? 
What is more remarkable still
What is the answer to all this? 
What is this but an acknowledgment of
What is your opinion? 
What then remains? 
What we do say is
When all has been said, there remains
When I look around me
When it can be shown that
When it is recognized that
When that is said, all is said
When we contemplate the
When we reflect on these sentiments
Where there is prejudice, it is no use to argue. 
Who finds fault with these things? 
Why should an argument be required to prove that
Why should it be necessary to confirm
Will you tell me how
With possibly a single exception
With regard to what has been stated

Yet it is plain
Yet, strange to say,
You and I may hold that
You can not assert that
You can not invent a series of argument
You can not say that
You do not pretend that
You have the authority of
