All Experience Is Subjective.

There Are No Monotone "values" In Biology.

Whenever We Pride Ourselves Upon Finding A Newer, Stricter Way Of Thought Or Exposition … We Lose Something Of The Ability To Think New Thoughts. And Equally, Of Course, Whenever We Rebel Against The Sterile Rigidity Of Formal Thought And Exposition And Let Our Ideas Run Wild, We Likewise Lose. As I See It, The Advances In Scientific Thought Come From A Combination Of Lose And Strict Thinking, And This Combination Is The Most Precious Tool Of Science.

Every Move We Make In Fear Of The Next War In Fact Hastens It.

Desired Substance, Things, Patterns, Or Sequences Of Experience That Are In Some Sense "good" For The Organism - Items Of Diet, Conditions Of Life, Temperature, Entertainment, Sex, And So Forth - Are Never Such That More Of The Something Is Always Better Than Less Of The Something. Rather, For All Objects And Experiences, There Is A Quantity That Has Optimum Value. Above That Quantity, The Variable Becomes Toxic. To Fall Below That Value Is To Be Deprived.

Our Initial Sensory Data Are Always "first Derivatives," Statements About Differences Which Exist Among External Objects Or Statements About Changes Which Occur Either In Them Or In Our Relationship To Them. Objects And Circumstances Which Remain Absolutely Constant Relative To The Observer, Unchanged Either By His Own Movement Or By External Events, Are In General Difficult And Perhaps Always Impossible To Perceive. What We Perceive Easily Is Difference And Change And Difference Is A Relationship.
