“I get it.”
“So when it was a question of ‘extended’ reality, Locke agreed with Descartes that it does have certain qualities that man is able to understand with his reason.”
“It shouldn’t be so difficult to agree on that.”
“Locke admitted what he called intuitive, or ‘demonstrative,’ knowledge in other areas too. For instance, he held that certain ethical principles applied to everyone. In other words, he believed in the idea of a natural right, and that was a rationalistic feature of his thought. An equally rationalistic feature was that Locke believed that it was inherent in human reason to be able to know that God exists.”
“Maybe he was right.”
“About what?”
“That God exists.”
“It is possible, of course. But he did not let it rest on faith. He believed that the idea of God was born of human reason. That was a rationalistic feature. I should add that he spoke out for intellectual liberty and tolerance. He was also preoccupied with equality of the sexes, maintaining that the subjugation of women to men was ‘man- made.’ Therefore it could be altered.”
“I can’t disagree there.”
“Locke was one of the first philosophers in more recent times to be interested in sexual roles. He had a great influence on John Stuart Mill, who in turn had a key role in the struggle for equality of the sexes. All in all, Locke was a forerunner of many liberal ideas which later, during the period of the French Enlightenment in the eighteenth century, came into full flower. It was he who first advocated the principle of division of powers...”
“Isn’t that when the power of the state is divided between different institutions?”
“Do you remember which institutions?”
“There’s the legislative power, or elected representatives. There’s the judicial power, or law courts, and then there’s the executive power, that’s the government.”
“This division of power originated from the French Enlightenment philosopher Montesquieu. Locke had first and foremost emphasized that the legislative and the executive power must be separated if tyranny was to be avoided. He lived at the time of Louis XIV, who had assembled all power in his own hands. ‘I am the State,’ he said. We say he was an ‘absolute’ ruler. Nowadays we would call Louis XIV’s rule lawless and arbitrary. Locke’s view was that to ensure a legal State, the people’s representatives must make the laws and the king or the government must apply them.”
Hume
…commit it then to the flames…
Alberto sat staring down at the table. He finally turned and looked out of the window.
“It’s clouding over,” said Sophie.
“Yes, it’s muggy.”
“Are you going to talk about Berkeley now?”
“He was the next of the three British empiricists. But as he is in a category of his own in many ways, we will first concentrate on David Hume, who lived from 1711 to 1776. He stands out as the most important of the empiricists. He is also significant as the person who set the great philosopher Immanuel Kant on the road to his philosophy.”
“Doesn’t it matter to you that I’m more interested in Berkeley’s philosophy?”
“That’s of no importance. Hume grew up near Edinburgh in Scotland. His family wanted him to take up law but he felt ‘an insurmountable resistance to everything but philosophy and learning.’ He lived in the Age of Enlightenment at the same time as great French thinkers like Voltaire and Rousseau, and he traveled widely in Europe before returning to settle down in Edinburgh toward the end of his life. His main work, A Treatise of Human Nature, was published when Hume was twenty-eight years old, but he claimed that he got the idea for the book when he was only fifteen.”
“I see I don’t have any time to waste.”
“You have already begun.”
“But if I were going to formulate my own philosophy, it would be quite different from anything I’ve heard up to now.”
“Is there anything in particular that’s missing?”
“Well, to start with, all the philosophers you have talked about are men. And men seem to live in a world of their own. I am more interested in the real world, where there are flowers and animals and children that are born and grow up. Your philosophers are always talking about ‘man’ and ‘humans,’ and now here’s another treatise on ‘human nature.’ It’s as if this ‘human’ is a middle-aged man. I mean, life begins with pregnancy and birth, and I’ve heard nothing about diapers or crying babies so far. And hardly anything about love and friendship.”
“You are right, of course. But Hume was a philosopher who thought in a different way. More than any other philosopher, he took the everyday world as his starting point. I even think Hume had a strong feeling for the way children—the new citizens of the world— experienced life.”
“I’d better listen then.”
“As an empiricist, Hume took it upon himself to clean up all the woolly concepts and thought constructions that these male philosophers had invented. There were piles of old wreckage, both written and spoken, from the Middle Ages and the rationalist philosophy of the seventeenth century. Hume proposed the return to our spontaneous experience of the world. No philosopher ‘will ever be able to take us behind the daily experiences or give us rules of conduct that are different from those we get through reflections on everyday life,’ he said.”
“Sounds promising so far. Can you give any examples?”
“In the time of Hume there was a widespread belief in angels. That is, human figures with wings. Have you ever seen such a creature, Sophie?”
“No.”
“But you have seen a human figure?”
“Dumb question.”
“You have also seen wings?”
“Of course, but not on a human figure.”
“So, according to Hume, an ‘angel’ is a complex idea. It consists of two different experiences which are not in fact related, but which nevertheless are associated in man’s imagination. In other words, it is a false idea which must be immediately rejected. We must tidy up all our thoughts and ideas, as well as our book collections, in the same way. For as Hume put it: If we take in our hands any volume ... let us ask, ‘Does it contain any abstract reasoning concerning quantity or number?’ No. ‘Does it contain any experimental reasoning concerning matter of fact and existence?’ No. Commit it then to the flames, for it can contain nothing but sophistry and illusion.”
“That was drastic.”
“But the world still exists. More fresh and sharply outlined than ever. Hume wanted to know how a child experiences the world. Didn’t you say that many of the philosophers you have heard about lived in their own world, and that you were more interested in the real world?”
“Something like that.”
“Hume could have said the same thing. But let us follow his train of thought more closely.”
“I’m with you.”
“Hume begins by establishing that man has two different types of perceptions, namely impressions and ideas. By ‘impressions’ he means the immediate sensation of external reality. By ‘ideas’ he means the recollection of such impressions.”
“Could you give me an example?”
“If you burn yourself on a hot oven, you get an immediate ‘impression.’ Afterward you can recollect that you burned yourself. That impression insofar as it is recalled is what Hume calls an ‘idea.’ The difference is that an impression is stronger and livelier than your reflective memory of that impression. You could say that the sensation is the original and that the idea, or reflection, is only a pale imitation. It is the impression which is the direct cause of the idea stored in the mind.”
“I follow you—so far.”
“Hume emphasizes further that both an impression and an idea can be either simple or complex. You
