Logic And Mathematics Are Nothing But Specialised

I Am Convinced That There Is No Sort Of Boundary Between The Living And The Mental Or Between The Biological And The Psychological. From The Moment An Organism Takes Account Of A Previous Experience And Adapts To A New Situation, That Very Much Resembles Psychology.

It Is With Children That We Have The Best Chance Of Studying The Development Of Logical Knowledge, Mathematical Knowledge, Physical Knowledge, And So Forth.

During The Earliest Stages The Child Perceives Things Like A Solipsist Who Is Unaware Of Himself As Subject And Is Familiar Only With His Own Actions.

It Is As His Own Mind Comes Into Contact With Others That Truth Will Begin To Acquire Value In The Child's Eyes And Will Consequently Become A Moral Demand That Can Be Made Upon Him. As Long As The Child Remains Egocentric, Truth As Such Will Fail To Interest Him And He Will See No Harm In Transposing Facts In Accordance With His Desires.

At One Time, Many Philosophers Held That Faultless "laws Of Thought" Were Somehow Inherent, A Priori, In The Very Nature Of Mind. This Belief Was Twice Shaken In The Past Century; First When Russell And His Successors Showed How The Logic Men Employ Can Be Defective, And Later When Freud And Piaget Started To Reveal The Tortuous Ways In Which Our Minds Actually Develop.
