The term "Scientific Rationalism" is really quite simple if you look at the roots of the meaning. "Rationalism", as we know, represents the term "reason" and simply expresses a better path to knowledge than using non-rational sources like superstition, myth, or just experience or observation. The whole idea is about thinking rationally when approaching a problem looking at reasonable solutions through the use of logic rather than 'gut' feeling or superstition. The ancient greeks were familiar with the concept of "rationalism." It was Descartes that insisted that knowledge can rest on a secure foundation through

- Reason.

Explanation:

'Scientific rationalism' is characterized as the principle that gave chief importance to reason and considered rationality or logic to be the key source in discovering knowledge or justification(as true or false) instead of emotional responses or religious beliefs.

As per the question, Descartes possessed a belief that 'knowledge can rest on a secure structure through reason'. His belief later served to be the basis of movement named 'scientific rationalism' which reemphasized the role of 'reason or logic' in gaining knowledge and reaching valuable as well as trustworthy conclusions. It focused on the use of a 'rational' approach and sources to reach valid solutions instead of adopting an 'emotional or religious' approach. Thus, 'reason' was the key emphasis of scientific rationalism.
