Yes, survival is primordial, basic and instinctual.
Emotions, etymologically, 'to move' are the basic modules that drive humans to move away (e.g. fear, sadness) from dangers that threaten survival and move towards (love, bonding) that which will enhance survival. To sustain the above, i.e. threatened or enhanced survival, the consequences of both are pain and pleasure respectively.
Logic is activated by the later 'higher' brain modules that evolved billions of years after the instinctual and limbic emotional brain the mid-brain.
Logic 'Alone' without the emotions meant there is no movements toward sustaining the primary purpose of survival at all costs. Logic when used rationally enhances and optimizes survival.
The instincts may seem logical, but that is only an after-thought that is imposed on what is going on by using language. Instincts are logical but it is not logic per-se.
For humanity, logic (not pure logic but rationality) is the most critical element to sustain optimal survival for humanity. However it must be used in complementary with the other basic faculties in a balanced way.
