In proportion to power is responsibility.

Remember this— that there is a proper dignity and proportion to be observed in the performance of every act of life.

Influence must ever be in proportion to property; and it is right it should.

Translation: Revenue and cost have to be in the right relation to each other.

A goal properly set is halfway reached.

The problem of doubling the cube was henceforth tried exclusively in the form of the problem of the two mean proportionals.

On symbolic use of equalities and proportions. Chapter II.
The analytical method accepts as proven the most famous [ as known from Euclid ] symbolic use of equalities and proportions that are found in items such as:
1. The whole is equal to the sum of its parts.
2. Quantities being equal to the same quantity have equality between themselves. [a = c & b = c => a = b]
3. If equal quantities are added to equal quantities the resulting sums are equal.
4. If equals are subtracted from equal quantities the remains are equal.
5. If equal equal amounts are multiplied by equal amounts the products are equal.
6. If equal amounts are divided by equal amounts, the quotients are equal.
7. If the quantities are in direct proportion so also are they are in inverse and alternate proportion. [a:b::c:d=>b:a::d:c & a:c::b:d]
8. If the quantities in the same proportion are added likewise to amounts in the same proportion, the sums are in proportion. [a:b::c:d => (a+c):(b+d)::c:d]
9.If the quantities in the same proportion are subtracted likewise from amounts in the same proportion, the differences are in proportion. [a:b::c:d => (a-c):(b-d)::c:d]
10. If proportional quantities are multiplied by proportional quantities the products are in proportion. [a:b::c:d & e:f::g:h => ae:bf::cg:dh]
11. If proportional quantities are divided by proportional quantities the quotients are in proportion. [a:b::c:d & e:f::g:h => a/e:b/f::c/g:d/h]
12. A common multiplier or divisor does not change an equality nor a proportion. [a:b::ka:kb & a:b::(a/k):(b/k)]
13. The product of different parts of the same number is equal to the product of the sum of these parts by the same number. [ka + kb = k(a+b)]
14. The result of successive multiplications or divisions of a magnitude by several others is the same regardless of the sequential order of quantities multiplied times or divided into that magnitude.
But the masterful symbolic use of equalities and proportions which the analyst may apply any time is the following:
15. If we have three or four magnitudes and the product of the extremes is equal to the product means, they are in proportion.[ad=bc => a:b::c:d OR ac=b² => a:b::b:c]
And conversely
10. If we have three or four magnitudes and the first is to the second as the second or the third is to the last, the product of the extremes is equal to that of means. [a:b::c:d => ad=bc OR a:b::b:c => ac=b²]
We can call a proportion the establishment of an equality [equation] and an equality [equation] the resolution of a proportion.

All is more or less proper to serve as a common measure, in proportion as it is more or less in general use, of a more similar quality, and more easy to be divided into aliquot parts. All is more or less applicable for the purpose of a general pledge of exchange, in proportion as it is less susceptible of decay or alteration in quantity or quality.

It would have been easy to think of the jobs in terms of that ratio between time and reward. But I knew what really counted was the relationship between time and results.

The end must justify the means.

Success in life is in direct proportion to what you do after you do what you are expected to do.

The measure of our rationality determines the degree of vividness with which we appreciate the needs of other life, the extent to which we become conscious of the real character of our own motives and impulses, the ability to harmonize conflicting impulses in our own life and in society, and the capacity to choose adequate means for approved ends.

As I have heretofore said, one can know many things which he cannot sense. One can, therefore, KNOW that balance in Nature's polarization principle DEMANDS equality of division in all of her paired effects.

The fundamental criterion for judging any procedure is the justice of its likely results.
