The distinguishing of the strata, or layers, in the embryonic membrane was a turning-point in the study of the history of evolution, and placed later researches in their proper light. A division of the (disc-shaped) embryo into an animal and a plastic part first takes place. In the lower part (the plastic or vegetative layer) are a serous and a vascular layer, each of peculiar organization. In the upper part also (the animal or serous germ-layer) two layers are clearly distinguishable, a flesh-layer and a skin-layer. (1828)
Primates stand at a turning point in the course of evolution. Primates are to the biologist what viruses are to the biochemist. They can be analysed and partly understood according to the rules of a simpler discipline, but they also present another level of complexity: viruses are living chemicals, and primates are animals who love and hate and think.
Life is always at some turning point.
The turning point, I think, was when I really realized that you can do it yourself. That you have to believe in you because sometimes that's the only person that does believe in your success but you.
I vividly remember a conversation I had many years ago in 1974, which marked a turning point in my leadership journey. I was sitting at a Holiday Inn with my friend, Kurt Campmeyer, when he asked me if I had a personal growth plan. I didn't. In fact, I didn't even know you were supposed to have one.
Politics can be relatively fair in the breathing spaces of history; at its critical turning points there is no other rule possible than the old one, that the end justifies the means.
I have had a few turning points, the first day I entered a gymnastics school at age 6.
...The two great turning-points of my life were when my father sent to Oxford, and when society sent me to prison.
In Italy, the country where fascism was born, we have a particular relation with the Holocaust, but as a turning point in history it belongs to everybody in the world. It is a part of humanity.
Up until I was 12 my sisters used to dress me up as a girl and introduce me as 'Claudia'! Twelve was a real turning point for me as I moved to a mixed school, and then I became cool and discovered hair gel.
These results add up to perhaps the most important investment lesson of all that can be drawn from this week's market anniversaries: Predicting turns in the market is incredibly difficult to do consistently well. That means that, if your investment strategy going forward is dependent on your anticipating major market turning points, your chances of success are extremely low.
The nineteenth century is a turning point in history, simply on account of the work of two men, Darwin and Renan, the one the critic of the Book of Nature, the other the critic of the books of God. Not to recognise this is to miss the meaning of one of the most important eras in the progress of the world.
I hate outlines. I have a broad sense of where the story is going; I know the end, I know the end of the principal characters, and I know the major turning points and events from the books, the climaxes for each book, but I don't necessarily know each twist and turn along the way. That's something I discover in the course of writing and that's what makes writing enjoyable. I think if I outlined comprehensively and stuck to the outline the actual writing would be boring.
More than any other time in history, the 1990s will be a turning point for human civilization.
There are two kinds of existentialist; first, those who are Christian...and on the other hand the atheistic existentialists, among whom...I class myself. What they have in common is that they think that existence precedes essence, or, if you prefer, that subjectivity must be the turning point.
I did a terrible television pilot that was so badly written and dumb that it became a turning point for me and I decided that I would never accept a job just because I needed the money.
Something is happening to Britain and the British. Or has happened. We are said to be passing through a transition, or a turning point, or a transformation; nobody is quite sure which.
The British Red Cross asked me to help them spearhead a fundraising campaign for the victims of the war in Nicaragua. It was a turning point in my life. It began my commitment to justice and human rights issues.
Many people are shrinking from the future and from participation in the movement toward a new, expanded reality. And, like homesick travelers abroad, they are focusing their anxieties on home. The reasons are not far to seek. We are at a turning point in human history. . . . We could turn our attention to the problems that going to the Moon certainly will not solve ... But I think this would be fatal to our future. . . . A society that no longer moves forward does not merely stagnate; it begins to die.
We have now reached a turning point in the struggle between freedom and terror.
