there’s father against child.
(Act 1, Sc.1, 115 - 118)
The “bias of nature” is defined as the natural inclination of the world. Throughout the play King Lear, the unnatural inclination of nature, supernatural properties and animal imageries are used by Shakespeare to illustrate the chaotic state of England, which was caused by the treacheries of the evil characters.
Gloucester is a character in the play who firmly believed that man’s fate has supernatural properties that are controlled or reflected by the heaven and stars: These late eclipses in the sun and moon
Portend us to no good. Though the wisdom of
nature can reason it thus and thus, yet nature finds
itself scourged by the sequent events.
(Act 1, Sc. 2, 109 - 113)
This is proclaimed by Gloucester as he is told by Edmund of Edgar’s supposedly treacherous plot to remove him from power. Gloucester’s trust in Edgar faltered as a result of Lear’s irrational banishment of Cordelia and Kent, coupled with recent anomalies in the heavens.

Edmund, the treacherous and bastard son of Gloucester, exploits Gloucester’s blind believe in the stars in his plot to oust Edgar out of the inheritance and ultimately to gain all of Gloucester’s wealth and land:
