Teaching is useless

Intellect is invisible to those have none.

– Arthur Schopenhauer

Teaching is useless. Information is useful. Although intelligence can seldom be increased, giving relevant information to a GOOD person so that he can fully realize his existing intelligence potential is always useful.

The intelligence-absorption principle should actually be called the information-absorption principle, because intelligence cannot be increased directly.

「智攝原則」應該改稱為「資攝原則」，因為你沒有可能，直接增加別人的智力。你可以做到的，就只有透過給予相關資料，去加快別人智力潛能的發展。換句話說，你只可以破除無知，而不可刪減愚蠢。

Information is just like technology: Intellectually challenging to create doesn’t mean intellectually challenging to use.

You cannot teach a man anything, you can only help him to find it for himself.

Eleven dimensions of color

Posted on by

Diclaimer: I have full-color vision, but with color blindness there are (roughly) two dimensions of color, whereas most people have three (and a black and white photograph has one). What this means is that with 1D color, you can sort all of the colors you see into a line — dark to light. With 2D color, you can sort all of the colors you see on a flat plane. With 3D color, you require stacking colors.

Now, there’s plenty of animals out there that have more than 3 dimensional color (they have more than 3 types of cone cells). So two colors that look the same for a normal person will look completely different for an animal. Some octopi have eleven dimensions of color! To them almost every human would be severely colorblind.

…

It’s thought that some people might be tetrachromats. They have 4 types of cone cells because of a genetic mutation. There’s still some questions on how this extra information is processed by the brain, but there’s a chance that for these people almost everyone else seems colorblind. They are able to distinguish two colors that everyone else cannot. This also means that television won’t reproduce colors correctly for them, and it won’t look natural.

想不出來 1.2

I’ve found that people who are great at something are not so much convinced of their own greatness as mystified at why everyone else seems so incompetent.

– Paul Graham

If you have really mastered a skill, it has already become your second instinct, and then you will seldom notice it.

The longer I live the more I see that I am never wrong about anything, and that all the pains that I have so humbly taken to verify my notions have only wasted my time.

– George Bernard Shaw

To believe your own thought, to believe that what is true for you in your private heart is true for all men — that is genius.

想不出來 1.1

Posted on by

這段改編自 2010 年 3 月 20 日的對話。

我以前在不知不覺間，假設了別人會知我所知東西；又或者，連我都想得出的東西，別人都會想得出。我有這類假設，是「自我中心」的一個表現。我後來發覺，我的這類假設，有很多時是錯的。

實情是，我想到的東西，別人未必想到；反之亦然。從是教學的人，尤其要留意這一點。

The why of love, 2.1.3

軟硬智力 7.1.3

.

How to answer this kind of questions:

Why am I so stupid?

It is not a valid question. It is not the case that there is a pre-existing “I”, to which we can assign some qualities such as stupidity. Instead, I am the sum of all my qualities, including the quality of being stupid.

— Me@2011.10.18

.

This kind of questions are like

Why does a triangle have three angles?

To be not stupid, the correct approach should be,

I am stupid. So I have to change my ‘I’ in order to be not stupid.

Although you cannot change the number of angles of a triangle, you can change the figure itself, replacing it with a rectangle.

If you do not believe me, imagine who am “I”, without all my qualities.

In other words, after deleting all my qualities, what would remain for “I”?

To improve is to change; to be perfect is to change often.

— Winston Churchill

change = delete the old one + create a new one

— Me@2010.11.28

.

It is difficult to change oneself because it is to change not just some qualities, but also the very definition of oneself. It is to change the identity.

You have to give up part of your original self in order to become a better one.

Qualities are not some external things. Qualities are what define you.

That’s why it is impossible to change your qualities; unless you are willing to redefine yourself; by replacing your present self with a better version.

That’s why you cannot change another person; unless he is willing to change.

“Why do you love me?” is not a correct question,

because

you = summation of all your qualities

— Me@2011.10.15

.

“Why do you love me?”

I love you because of your good qualities.

.

“What if I do not have such qualities anymore?”

I love you for your good character.

.

“What if I do not have such a good character anymore?”

Then you are not you anymore.

The classic Buddhist image of this hack is that thoughts are like clouds passing through a spacious blue sky. All your life, you’ve been convinced that this succession of clouds comprises a stable, enduring identity — a “self.” But Buddhists believe this self this is an illusion that causes unnecessary suffering as you inevitably face change, loss, disease, old age, and death. One aim of practice is to reveal the gaps or discontinuities — the glimpses of blue sky — between the thoughts, so you’re not so taken in by the illusion, but instead learn to identify with the panoramic awareness in which the clouds arise and disappear.
