A Quote by Jean-Baptiste Lamarck
However, if we consider that all the characteristics which have been cited are only differences in degree of structure, may we not suppose that this special condition of organization of man has been gradually acquired at the close of a long period of time, with the aid of circumstances which have proved favorable? What a subject for reflection for those who have the courage to enter into it!

True depression is a terribly real thing. Some of the noblest men and women in the world have been prone to it ... They may have no reason for feeling more unhappy at that particular period than at any other. Their worldly circumstances may be just what they have been for a long time past, and perfectly satisfactory. But there suddenly closes down on them a fog of the mind which exaggerates and distorts everything.
In however complex a manner this feeling may have originated, as it is one of high importance to all those animals which aid and defend one another, it will have been increased through natural selection; for those communities, which included the greatest number of the most sympathetic members, would flourish best, and rear the greatest number of offspring.
It is so natural for us to consider our presence as indispensable in the world, so long as we have much to do in it, that the wisdom of retiring wholly from employments in advanced life may be questioned. Certainly, he who does so is in danger of finding, before long, that he has only given up the occupation to which he has been accustomed, for the new business of calculating the period of his decease.
No man will subject himself to the ridicule of pretending that any natural connection subsists between the sun or the seasons, and the period within which human virtue can bear the temptations of power. Happily for mankind, liberty is not, in this respect, confined to any single point of time, but lies within extremes, which afford sufficient latitude for all the variations which may be required by the various situations and circumstances of civil society.
I consider the differences between man and animals in propensities, feelings, and intellectual faculties, to be the result of the same cause as that which we assign for the variations in other functions, viz. difference of organization; and that the superiority of man in rational endowments is not greater than the more exquisite, complicated, and perfectly developed structure of his brain, and particularly of his ample cerebral hemispheres, to which the rest of the animal kingdom offers no parallel, nor even any near approximation, is sufficient to account for.
The morphological characteristics of plant and animal species form the chief subject of the descriptive natural sciences and are the criteria for their classification. But not until recently has it been recognized that in living organisms, as in the realm of crystals, chemical differences parallel the variation in structure.
In general it may be said that the things which we take for granted without inquiry or reflection are just the things which determine our conscious thinking and decide our conclusions. And these habitudes which lie below the level of reflection are just those which have been formed in the constant give and take of relationship with others.
The mere size of the brain has been proved to be no measure of superiority. The woman has greater moral courage than the man; she has also special gifts which enable her to govern in moments of danger and crisis. If necessary she can become a warrior.
To me... it appears that there have been differences of opinion and party differences, from the first establishment of government to the present day, and on the same question which now divides our own country; that these will continue through all future time; that every one takes his side in favor of the many, or of the few, according to his constitution, and the circumstances in which he is placed.
A man who has made up his mind on a given subject twenty-five years ago and continues to hold his political opinions after he has been proved to be wrong is a man of principle; while he who from time to time adapts his opinions to the changing circumstances of life is an opportunist.
The one and only substitute for experience which we have not ourselves had is art, literature. We have been given a miraculous faculty: Despite the differences of language, customs and social structure we are able to communicate life experience from one whole nation to another, to communicate a difficult national experience many decades long which the second of the two has never experienced.
A man's character never changes radically from youth to old age. What happens is that circumstances bring out characteristics which have not been obvious to the superficial observer.
We shall see that the mathematical treatment of the subject [of electricity] has been greatly developed by writers who express themselves in terms of the 'Two Fluids' theory. Their results, however, have been deduced entirely from data which can be proved by experiment, and which must therefore be true, whether we adopt the theory of two fluids or not. The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.
The more progress physical sciences make, the more they tend to enter the domain of mathematics, which is a kind of centre to which they all converge. We may even judge the degree of perfection to which a science has arrived by the facility with which it may be submitted to calculation.
Nothing is more unjust, however common, than to charge with hypocrisy him that expresses zeal for those virtues which he neglects to practice; since he may be sincerely convinced of the advantages of conquering his passions without having yet obtained the victory as a man may be confident of the advantages of a voyage or a journey, without having courage or industry to undertake it, and may honestly recommend to others those attempts which he neglects himself.
Love is a condition so powerful; it may be that which pulls the stars in the firmament. It may be that which pushes and urges the blood in the veins. Courage: you have to have courage to love somebody because you risk everything-ever ything.
