Perceived by the senses is fact 
state of things, relation of things 
Conscious mental condition - a fact. 
Certain objects in a certain order 
In a certain place - a fact 
Heard and saw something - a fact 
Said certain words - a fact 
Hold certain opinion - a fact 
Certain reputation - a fact  
Intention sensation - facts. 
Going on facts and using facts 
Are sufficient I am not telling 
As a poet my dear.
