If, then, I should here rest my cause
If there be any among us
If there be one lesson more than another
If this be so
If this seems doubtful to anyone
If, unhappily, the day should ever come
If we accept at all the argument
If we are not blind to
If we are rightly informed
If we are to reason on the fact
If we cast our glance back
If we embark upon a career
If we had the whole case before us
If we isolate ourselves
If we may trust to experience
If we pursue a different course
If we pursue our inquiries through
If we sincerely desire
If we survey
If we would not be beguiled
If what has been said is true
If you remain silent
If you seek the real meaning of
If you think for a moment
If you want to look
If you were asked to point out
If you will allow me to prophesy
If you will forgive me the expression
If you wish for a more interesting example
If you wish to get at the bottom of facts
If you would see the most conclusive proof
If your view is right
In a significant paragraph
In a wider sense
In a word, gentlemen
In a word, I conceive
In actual life, I suspect
In addition to these arguments
In addressing myself to the question
In addressing you I feel
In agreement with this obvious conclusion
In all ages of the world
In all or any of these views
In all times and places
In an unguarded moment
In answering the inquiry
In any view of the case
In closing my speech, I ask each of you
In conclusion, let me say
In conclusion, may I repeat
