Are there any differences between these three sets:

> からして、からすると、からすれば

vs.

> から見て、から見ると、から見れば

vs.

> から言って、から言うと、から言えば

These 'sets' seem to be used in 2 basic ways:

  1. Presents something as a basis for judgment. 
  2. To mean "From the point of view of..."

However, are there any restraints or special requirements when using these?
Are they simply interchangeable?

For example are all of the following sentences acceptable?

  1. Presents something as a basis for judgment. 

    * 症状から **すると** 、心臓の病気かもしれません。 
    * 症状から **見ると** 、心臓の病気かもしれません。 
    * 症状から **言うと** 、心臓の病気かもしれません。 
  2. "From the point of view of..." 

    * 昔の人から **すると** 、まるで別世界です。 
    * 昔の人から **見ると** 、まるで別世界です。 
    * 昔の人から **言うと** 、まるで別世界です。

The difference between からすると、から見ると、から言うと?
First of all, even the intra-set items are not the same. Meaning that, for
example, `からすると` is not even the same as `からして`, etc. I don't have the
proficiency to discuss the differences between every possible combination of
items, but I do have a strong grasp of the difference between `からすると` and
`からして`, if it helps. I would speculate that the other items have a similar
difference in nuance.

Basically, `からすると` is a completely objective judgement. Imagine, for example,
that you're sitting around a table with some guys and a girl walks by that
catches your interest (swap the sexes around if you prefer). Your friend says
"Ooooh, she's cute. I wonder if she's spoken for." You look at her finger and
see that she's not wearing a ring, so you say "Well, judging by the fact that
she's not wearing a ring, I'd say she's fair game." This is `からすると`. You
didn't know this girl before, you had no preconception about whether or not
she might be single, you used the facts and nothing but the facts to arrive at
a judgement.

Now imagine a slightly different version of the same scenario. Her shirt says
"I'm available" on it, so you go up and talk to her and she says, much to your
surprise, that she's taken. You go back to your friends and say "WTF, even her
shirt says she's available!". I'm sure someone will provide a more idiomatic
translation, but for the purposes of illustration, you could translate this:

> シャツからして、独身女性と思ったんだよ。

Here, it wasn't a completely objective judgement. You had a preformed opinion
about this person, and you are singling out one aspect of your opinion for
emphasis.

As a general rule of thumb, I like to translate `からすると` as "judging from" or
"judging by", and I like to translate `からして` as "Even **__** ", as in the
above example. `からして` sentences tend to require structural modifications to
the English counterpart to translate idiomatically.

I suspect `からすれば` is still different, but I will let others comment.

answer
First of all, からして is a different grammatical construction. As Zach has
already covered this in more detail in his answer, I will skip over it. And as
Dave M G stated in _his_ answer, all of these constructions have the meaning
of "judging from the position of X."

**Where they differ is in their usage** , rather than their meaning.

**～から言うと / ～から見ると**

With these two, what follows must be something which contains the speaker's
own thoughts, feelings, or opinion. What differentiates them is that with
～から見ると, the noun that goes in ～ may be a person, while it with ～から言うと, it may
not. Examples:

>   * × 彼からいうと、それは間違っているそうだ。
>   * ○ 彼の考え方からいうと、それは間違っているそうだ。
>   * ○ 彼から見ると、それは間違っているそうだ。
>

Also seen as: ～からいえば, ～からいって, ～からいったら and ～から見れば, ～から見て, ～から見ても, ～から見たら

**～からすると**

What differentiates ～からすると from the others is that what follows it doesn't
necessarily have to be the speaker's thoughts, feelings, or opinion (but if it
is, that's okay, too). Examples:

>   * ○ 私の予想からすると、真夏日も後数日だろう。
>   * × 私の予想から見ると、真夏日も後数日だろう。(× because 予想 and 見る have the same meaning here.)
>   * ○ いつもよく食べる彼女が食欲ないことからすると、何かあったのだろうか。
>   * ○ いつもよく食べる彼女が食欲ないことからすると、何かあったと思う。
>

Also seen as: ～からすれば, ～からしたら, ～からして

So essentially, every instance of ～からいうと can be replaced just fine with either
～からすると or ～から見ると, but the reverse is not necessarily true.

_Note:_ According to the textbooks I used as reference when researching this
answer, ～からして, while it can be used in this sense, is slightly different (as
can be the other forms of ～からすると). It acts as an intensifier, basically
meaning **only** thinking about it from that point of view.

**Applying the Principles**

Now, if we apply these principles to the examples given in your question, we
can easily come to a conclusion on their acceptability.

>   * ○ 症状からすると、心臓の病気かもしれません。
>   * ○ 症状から見ると、心臓の病気かもしれません。
>   * ○ 症状から言うと、心臓の病気かもしれません。
>

I believe all of these are just fine, because 1) the noun prior to the
expressions is not a person, and 2) what follows is the speaker's opinion. The
next set is a little bit different, however.

>   * × 昔の人からすると、まるで別世界です。
>   * ○ 昔の人から見ると、まるで別世界です。
>   * × 昔の人から言うと、まるで別世界です。
>

In this case, only ～から見ると is valid, because only this expression can be from
the "point of view" of a person (in this case, 昔の人).

**Summary**

In sum, while **the meaning** of these three expressions is for all intents
and purposes **the same** , **their usage is slightly different**. In my
opinion (自分の意見からいうと(?) :p) the differences are actually due to the slight
variations in meaning, but I don't really have anything to back me up on that.

Note in the interest of transparency: Much of my answer (including the
examples used) is based the explanation in [this textbook on a Chinese
website](http://wenku.baidu.com/view/2bdb4c7b1711cc7931b716ca.html). As the
site in Chinese, that's about as much as I can tell you about it. :)
