"A woman seldom writes her mind but in her postscript"

This quote by Richard Steele suggests that females typically keep back their true ideas and sensations, just exposing them in a postscript. A postscript is an additional note or message included at the end of a letter, often after the signature. This could be translated as ladies being hesitant to express themselves honestly and directly, rather choosing to add their real ideas as an afterthought. It might likewise suggest that ladies are expected to comply with societal standards and expectations, and therefore feel the need to hide their true viewpoints. Overall, this quote highlights the idea that ladies may not constantly feel comfortable or empowered to speak their minds freely.
