The quote "’Tis within ourselves that we are thus or thus" from Shakespeare's play Othello suggests that our true nature and identity are determined by our internal choices and dispositions, rather than external factors. It emphasizes the idea that individuals possess the power to shape their own characteristics and respond to circumstances based on personal will and introspection.

This sentiment reflects a broader theme in Shakespeare's work, where characters often grapple with their inner lives and moral choices. It serves as a reminder that self-awareness and personal responsibility play critical roles in our actions, ultimately influencing our destinies and interactions with others.
