The wish to preserve oneself is the symptom of a condition of distress, of a limitation of the really fundamental instinct of life which aims at the expansion of power and, wishing for that, frequently risks and even sacrifices self-preservation. It should be considered symptomatic when some philosophers–for example, Spinoza who was consumptive–considered the instinct of self-preservation decisive and had to see it that way; for they were individuals in conditions of distress.

Like every living thing its prime characteristic is a blind, unreasoned instinct to survive.

Human institutions depend for their existence and stability on the impulse of self-preservation and its close associate, — the fear instinct.

Self-preservation is the central aim of all life-activities.

Plainly stated, I believe consciousness is an instinct. Many organisms, not just humans, come with it, ready-made. That is what instincts are, something organisms come with. Living things have an organization that allows life and ultimately consciousness to exist, even though they are made from the same materials as the non-living natural world that surrounds them. And instincts envelop organisms from bacteria to humans. Survival, sex, resilience, and walking are commonly thought to be instincts, but so, too, are more complex capacities such as language and sociality — all are instincts. The list is long, and we humans seem to have more instincts than other creatures. Yet there is something special about the consciousness instinct. It is no ordinary instinct. In fact, it seems so extraordinary that many think only we humans can lay claim to it. Even if that’s not the case, we want to know more about it. And because we all have it, we all think we have insight into it. As we will see, it is a slippery, complex instinct situated in the universe’s most impenetrable organ, the brain.

They say that the first inclination which an animal has is to protect itself.

We are human animals and thus fear death as animals do. The so-called “will to live” is nothing more than a different name for animal instinct. I am but one of these human animals, and when I observe my loss of interest in food and women, I realize I have gradually lost this animal instinct. Now I reside in a world of diseased nerves, as translucent as ice.

The impulsive desire to save human life when in peril is one of the most beneficial instincts of humanity, and is nowhere more salutary in its results than in bringing help to those who, exposed to destruction from the fury of winds and waves, would perish if left without assistance.

Since the survival impulse in nature is transmuted into two different and contradictory spiritualized forms, which we may briefly designate as the will-to-live-truly and the will-to-power, man is at variance with himself. The power of the second impulse places him more fundamentally in conflict with his fellowman than democratic liberalism realizes.

Man does not seem able to “help” his selfishness; it seems to come from his animal nature. Through countless ages of evolution the organism has had to protect its own integrity; it had its own physiochemical identity and was dedicated to preserving it. This is one of the main problems in organ transplants: the organism protects itself against foreign matter, even if it is a new heart that would keep it alive. The protoplasm itself harbors its own, nurtures itself against the world, against invasions of its integrity. It seems to enjoy its own pulsations, expanding into the world and ingesting pieces of it. If you took a blind and dumb organism and gave it self-consciousness and a name, if you made it stand out of nature and know consciously that it was unique, then you would have narcissism. In man, physiochemical identity and the sense of power and activity have become conscious.

There are two fundamentally different ways for the strong to bend down to the weak, for the rich to help the poor, for the more perfect life to help the “less perfect.” This action can be motivated by a powerful feeling of security, strength, and inner salvation, of the invincible fullness of one’s own life and existence. All this unites into the clear awareness that one is rich enough to share one’s being and possessions. Love, sacrifice, help, the descent to the small and the weak, here spring from a spontaneous overflow of force, accompanied by bliss and deep inner calm. Compared to this natural readiness for love and sacrifice, all specific “egoism,” the concern for oneself and one’s interest, and even the instinct of “self-preservation” are signs of a blocked and weakened life. Life is essentially expansion, development, growth in plenitude, and not “self-preservation,” as a false doctrine has it. Development, expansion, and growth are not epiphenomena of mere preservative forces and cannot be reduced to the preservation of the “better adapted.” … There is a form of sacrifice which is a free renunciation of one’s own vital abundance, a beautiful and natural overflow of one’s forces. Every living being has a natural instinct of sympathy for other living beings, which increases with their proximity and similarity to himself. Thus we sacrifice ourselves for beings with whom we feel united and solidary, in contrast to everything “dead.” This sacrificial impulse is by no means a later acquisition of life, derived from originally egoistic urges. It is an original component of life and precedes all those particular “aims” and “goals” which calculation, intelligence, and reflection impose upon it later. We have an urge to sacrifice before we ever know why, for what, and for whom! Jesus’ view of nature and life, which sometimes shines through his speeches and parables in fragments and hidden allusions, shows quite clearly that he understood this fact. When he tells us not to worry about eating and drinking, it is not because he is indifferent to life and its preservation, but because he sees also a vital weakness in all “worrying” about the next day, in all concentration on one’s own physical well-being. … all voluntary concentration on one’s own bodily wellbeing, all worry and anxiety, hampers rather than furthers the creative force which instinctively and beneficently governs all life. … This kind of indifference to the external means of life (food, clothing, etc.) is not a sign of indifference to life and its value, but rather of a profound and secret confidence in life’s own vigor and of an inner security from the mechanical accidents which may befall it. A gay, light, bold, knightly indifference to external circumstances, drawn from the depth of life itself—that is the feeling which inspires these words! Egoism and fear of death are signs of a declining, sick, and broken life. … This attitude is completely different from that of recent modern realism in art and literature, the exposure of social misery, the description of little people, the wallowing in the morbid—a typical ressentiment phenomenon. Those people saw something bug-like in everything that lives, whereas Francis sees the holiness of “life” even in a bug.

We are therefore driven by both basic survival instincts and rational thought.

Is there any instinct more deeply implanted in the heart of man than the pride of protection, a protection which is constantly exerted for a fragile and defenceless creature?

Whenever human activity is directed exclusively to the service of the instinct for self-preservation it is called theft or usury, robbery or burglary etc
