Tabula rasa (Latin: "scraped tablet," though often translated "blank slate") is the notion, popularized by John Locke (1632 – 1704).
Locke is a philosopher whose concept known as tabula rasa, which literally means blank sheet of paper, means that people aren’t born with innate ideas. Infants must learn from an educator and as the person grows up he/she will fill that empty brain with knowledge. He stresses on the fact that experience is everything in terms of education.
The Social Contract (1762), by Jean-Jacques Rousseau
‘Man is born free, and everywhere he is in chains. Here’s one who thinks he is the master of others, yet he is more enslaved than they are.’
Rousseau says, unlike Locke, that humans are blank slates but rather that they come into the world with compassion and self-preservation, and the rest of their education needs to be learned through man, nature and things (experiences). Therefore he believes that humans by nature have the potential to do well and be good. The only thing that hinders people from innocence is the influence others have that can corrupt them.
