It Is... Easy To Be Certain. One

The Percept Is The Reality. It Is Not In Propositional Form. But The Most Immediate Judgment Concerning It Is Abstract. It Is Therefore Essentially Unlike The Reality, Although It Must Be Accepted As True To That Reality. Its Truth Consists In The Fact That It Is Impossible To Correct It, And In The Fact That It Only Professes To Consider One Aspect Of The Percept.

Truth Is That Concordance Of An Abstract Statement With The Ideal Limit Towards Which Endless Investigation Would Tend To Bring Scientific Belief, Which Concordance The Abstract Statement May Possess By Virtue Of The Confession Of Its Inaccuracy And One-sidedness, And This Confession Is An Essential Ingredient Of Truth.

If An Opinion Can Eventually Go To The Determination Of A Practical Belief, It, In So Far, Becomes Itself A Practical Belief; And Every Proposition That Is Not Pure Metaphysical Jargon And Chatter Must Have Some Possible Bearing Upon Practice.

All The Evolution We Know Of Proceeds From The Vague To The Definite.

We Cannot Begin With Complete Doubt.
