What is the main conflict in Equus by Peter Shaffer?

“Equus” is a 1974 Tony Award-winning play written by Peter Schaffer and published in 1973. It details the efforts of Dr. Martin Dysart to get to the root of the problems affecting neurotic seventeen year-old Alan Strang, who has blinded six horses with a pick at the stable where he works. Dysart is reluctant to take the case on, because he is overworked, but ultimately agrees to do so. Yet his experiences with Alan ultimately disturb him, and make him question the fundamentals of his own work.
