The reading of all good books is like a conversation with the finest minds of past centuries.

The only secure knowledge is that I exist.
Interpretation
What this quote means
The essence of knowledge is self-awareness and existence.
In this quote, René Descartes emphasizes the foundation of knowledge and certainty as rooted in one's own existence. He suggests that while many things can be uncertain, the very act of thinking and recognizing oneself as a conscious being is the only undeniable truth—a cornerstone of philosophical inquiry known as 'cogito, ergo sum' or 'I think, therefore I am.'

Rene DescartesRead
Before examining this more carefully and investigating its consequences, I want to dwell for a moment in the contemplation of God, to ponder His attributes in me, to see, admire, and adore the beauty of His boundless light, insofar as my clouded insight allows. Believing that the supreme happiness of the other life consists wholly of the contemplation of divine greatness, I now find that through less perfect contemplation of the same sort I can gain the greatest joy available in this life.

People talk of “social outcasts.” The words apparently denote the miserable losers of the world, the vicious ones, but I feel as though I have been a “social outcast” from the moment I was born. If ever I meet someone society has designated as an outcast, I invariably feel affection for him, an emotion which carries me away in melting tenderness.
