1. Knowledge Comes from Reason, Not Senses
One day, Arjun touched a hot cup of tea and said, “Ah! It’s hot.” But then he thought, “What
if someone else touches the same cup and feels it dierently?” His teacher said, “That’s why
Raonalists believe that our senses can somemes deceive us. True knowledge doesn’t
come from what we see or touch — it comes from thinking and reasoning.”
So the rst teaching of Raonalism is:
“Reason is the primary source of knowledge.”
Famous Raonalist philosophers like René Descartes, Baruch Spinoza, and Goried Leibniz
all believed that pure thought can lead us to truths that are universal and unchanging –
unlike our senses which oen change.
2. Innate Ideas Exist in the Mind
Arjun once asked, “How do babies know how to cry for food? Who taught them that?” His
teacher smiled and said, “Some knowledge is already inside us from birth.”
Raonalists believe in something called innate ideas – these are ideas we are born with, like
the idea of God, morality, mathemacs, or perfecon. Descartes famously said that we all
have a natural idea of a perfect being (God), and we didn’t learn it from outside – it was
already within us.
So, second teaching of Raonalism is:
“The mind contains ideas that are present from birth.”
It’s like saying, you don’t have to see every triangle in the world to know that the sum of its
angles is always 180° – your mind can understand it just by reasoning.
3. Deducve Logic Over Empirical Evidence
Let’s say Arjun hears someone say, “All humans are mortal. Socrates is a human. Therefore,
Socrates is mortal.” This is deducve reasoning – starng from general truths and reaching
specic conclusions.
Raonalists love this method. They believe that using logic, step-by-step, can bring us closer
to truth. They value this more than experiments or observaons.
Thus, the third teaching of Raonalism is:
“Truth can be discovered through deducve logic and reasoning.”
Think of it like solving a math problem — you don’t need to go outside and measure things.
You just sit, think, and use your brain.
